                               for sendfile operations.  Advisory only,
                               apr_sendfile does not check this flag.
perm Access permissions for file.
pool The pool to use.
Remarks:
If perm is APR_OS_DEFAULT and the file is being created, appropriate default permissions will be used. *arg1 must point to a valid file_t, or NULL (in which case it will be allocated)

apr_status_t apr_file_open_stderr ( apr_file_t **  thefile,
apr_pool_t *  cont 
)

open standard error as an apr file pointer.

Parameters:
thefile The apr file to use as stderr.
cont The pool to allocate the file out of.
Remarks:
The only reason that the apr_file_open_std* functions exist is that you may not always have a stderr/out/in on Windows. This is generally a problem with newer versions of Windows and services.
The other problem is that the C library functions generally work differently on Windows and Unix. So, by using apr_file_open_std* functions, you can get a handle to an APR struct that works with the APR functions which are supposed to work identically on all platforms.

apr_status_t apr_file_open_stdin ( apr_file_t **  thefile,
apr_pool_t *  cont 
)

open standard input as an apr file pointer.

Parameters:
thefile The apr file to use as stdin.
cont The pool to allocate the file out of.
Remarks:
The only reason that the apr_file_open_std* functions exist is that you may not always have a stderr/out/in on Windows. This is generally a problem with newer versions of Windows and services.

apr_status_t apr_file_open_stdout ( apr_file_t **  thefile,
apr_pool_t *  cont 
)

open standard output as an apr file pointer.

Parameters:
thefile The apr file to use as stdout.
cont The pool to allocate the file out of.
Remarks:

apr_fileperms_t  perms 
)

set the specified file's permission bits.

Parameters:
fname The file (name) to apply the permissions to.
perms The permission bits to apply to the file.
Warning:
Some platforms may not be able to apply all of the available permission bits; APR_INCOMPLETE will be returned if some permissions are specified which could not be set.
Platforms which do not implement this feature will return APR_ENOTIMPL.

apr_status_t apr_file_pipe_create ( apr_file_t **  in,
apr_file_t **  out,
apr_pool_t *  cont 
)

Parameters:
thepipe The pipe we are setting a timeout on.
timeout The timeout value in microseconds. Values < 0 mean wait forever, 0 means do not wait at all.

apr_pool_t* apr_file_pool_get ( const apr_file_t *  thefile  ) 

Get the pool used by the file.

int apr_file_printf ( apr_file_t *  fptr,

Returns:
The number of bytes written

apr_status_t apr_file_putc ( char  ch,
apr_file_t *  thefile 
)

put a character into the specified file.

Parameters:
ch The character to write.
thefile The file descriptor to write to

apr_status_t apr_file_puts ( const char *  str,
apr_file_t *  thefile 
)

Put the string into a specified file.

Parameters:
str The string to write.
thefile The file descriptor to write to

apr_status_t apr_file_read ( apr_file_t *  thefile,
void *  buf,
apr_size_t *  nbytes 
)

Read data from the specified file.

Parameters:
thefile The file descriptor to read from.
buf The buffer to store the data to.
nbytes On entry, the number of bytes to read; on exit, the number of bytes read.
Remarks:
apr_file_read will read up to the specified number of bytes, but never more. If there isn't enough data to fill that number of bytes, all of the available data is read. The third argument is modified to reflect the number of bytes read. If a char was put back into the stream via ungetc, it will be the first character returned.
It is not possible for both bytes to be read and an APR_EOF or other error to be returned.

APR_EINTR is never returned.

apr_status_t apr_file_read_full ( apr_file_t *  thefile,
void *  buf,
apr_size_t  nbytes,
apr_size_t *  bytes_read 
)

Read data from the specified file, ensuring that the buffer is filled before returning.

Parameters:
thefile The file descriptor to read from.
buf The buffer to store the data to.
nbytes The number of bytes to read.
bytes_read If non-NULL, this will contain the number of bytes read.
Remarks:
apr_file_read will read up to the specified number of bytes, but never more. If there isn't enough data to fill that number of bytes, then the process/thread will block until it is available or EOF is reached. If a char was put back into the stream via ungetc, it will be the first character returned.
It is possible for both bytes to be read and an error to be returned. And if *bytes_read is less than nbytes, an accompanying error is _always_ returned.

APR_EINTR is never returned.

apr_status_t apr_file_remove ( const char *  path,
apr_pool_t *  cont 
)

delete the specified file.

Parameters:
path The full path to the file (using / on all systems)
cont The pool to use.
Remarks:
If the file is open, it won't be removed until all instances are closed.

apr_status_t apr_file_rename ( const char *  from_path,
const char *  to_path,
apr_pool_t *  pool 
)

rename the specified file.

Parameters:
from_path The full path to the original file (using / on all systems)
to_path The full path to the new file (using / on all systems)
pool The pool to use.
Warning:
If a file exists at the new location, then it will be overwritten. Moving files or directories across devices may not be possible.

apr_status_t apr_file_seek ( apr_file_t *  thefile,
apr_seek_where_t  where,
apr_off_t *  offset 
)

Move the read/write file offset to a specified byte within a file.

Parameters:
thefile The file descriptor
where How to move the pointer, one of: 
            APR_SET  --  set the offset to offset
            APR_CUR  --  add the offset to the current position 
            APR_END  --  add the offset to the current file size
offset The offset to move the pointer to.
Remarks:
The third argument is modified to be the offset the pointer was actually moved to.

apr_status_t apr_file_setaside ( apr_file_t **  new_file,
apr_file_t *  old_file,
apr_pool_t *  p 
)

move the specified file descriptor to a new pool

Parameters:
new_file Pointer in which to return the new apr_file_t
old_file The file to move
p The pool to which the descriptor is to be moved
Remarks:
Unlike apr_file_dup2(), this function doesn't do an OS dup() operation on the underlying descriptor; it just moves the descriptor's apr_file_t wrapper to a new pool.

The new pool need not be an ancestor of old_file's pool.

After calling this function, old_file may not be used

apr_status_t apr_file_write ( apr_file_t *  thefile,
const void *  buf,
apr_size_t *  nbytes 
)

Write data to the specified file.

Parameters:
thefile The file descriptor to write to.
buf The buffer which contains the data.
nbytes On entry, the number of bytes to write; on exit, the number of bytes written.
Remarks:
apr_file_write will write up to the specified number of bytes, but never more. If the OS cannot write that many bytes, it will write as many as it can. The third argument is modified to reflect the * number of bytes written.
It is possible for both bytes to be written and an error to be returned.

APR_EINTR is never returned.

apr_status_t apr_file_write_full ( apr_file_t *  thefile,
const void *  buf,
apr_size_t  nbytes,
apr_size_t *  bytes_written 
)

Write data to the specified file, ensuring that all of the data is written before returning.

Parameters:
thefile The file descriptor to write to.
buf The buffer which contains the data.
nbytes The number of bytes to write.
bytes_written If non-NULL, this will contain the number of bytes written.
Remarks:
apr_file_write will write up to the specified number of bytes, but never more. If the OS cannot write that many bytes, the process/thread will block until they can be written. Exceptional error such as "out of space" or "pipe closed" will terminate with an error.
It is possible for both bytes to be written and an error to be returned. And if *bytes_written is less than nbytes, an accompanying error is _always_ returned.

APR_EINTR is never returned.

apr_status_t apr_file_writev ( apr_file_t *  thefile,
const struct iovec *  vec,
apr_size_t  nvec,
apr_size_t *  nbytes 
)

Write data from iovec array to the specified file.

Parameters:
thefile The file descriptor to write to.
vec The array from which to get the data to write to the file.
nvec The number of elements in the struct iovec array. This must be smaller than APR_MAX_IOVEC_SIZE. If it isn't, the function will fail with APR_EINVAL.
nbytes The number of bytes written.
Remarks:
It is possible for both bytes to be written and an error to be returned. APR_EINTR is never returned.
apr_file_writev is available even if the underlying operating system

doesn't provide writev().

apr_status_t apr_temp_dir_get ( const char **  temp_dir,
apr_pool_t *  p 
)

Find an existing directory suitable as a temporary storage location.

Parameters:
temp_dir The temp directory.
p The pool to use for any necessary allocations.
Remarks:
This function uses an algorithm to search for a directory that an an application can use for temporary storage. Once such a directory is found, that location is cached by the library. Thus, callers only pay the cost of this algorithm once if that one time is successful.
