flags	The flags that were used to open this file.
cont	The pool to use if it is needed.

Remarks

On Unix, it is only possible to put a file descriptor into an apr file type.

apr_status_t apr_os_imp_time_get	(	apr_os_imp_time_t **	ostime,
		apr_time_t *	aprtime
	)

Get the imploded time in the platforms native format.

Parameters

ostime	the native time format
aprtime	the time to convert

apr_status_t apr_os_imp_time_put	(	apr_time_t *	aprtime,
		apr_os_imp_time_t **	ostime,
		apr_pool_t *	cont
	)

Put the imploded time in the APR format.

Parameters

cont	the pool to use if necessary

const char* apr_os_locale_encoding

(

apr_pool_t *

pool

)

Get the name of the current locale character set.

Parameters

pool	the pool to allocate the name from, if needed

Remarks

Defers to apr_os_default_encoding if the current locale's data can't be retrieved on this system.

apr_status_t apr_os_pipe_put	(	apr_file_t **	file,
		apr_os_file_t *	thefile,
		apr_pool_t *	cont
	)

convert the file from os specific type to apr type.

Parameters

file	The apr file we are converting to.
thefile	The os specific pipe to convert
cont	The pool to use if it is needed.

Remarks

On Unix, it is only possible to put a file descriptor into an apr file type.

apr_status_t apr_os_pipe_put_ex	(	apr_file_t **	file,
		apr_os_file_t *	thefile,
		int	register_cleanup,
		apr_pool_t *	cont
	)

convert the file from os specific type to apr type.

Parameters

file	The apr file we are converting to.
thefile	The os specific pipe to convert
register_cleanup	A cleanup will be registered on the apr_file_t to issue apr_file_close().
cont	The pool to use if it is needed.

Remarks

On Unix, it is only possible to put a file descriptor into an apr file type.

apr_status_t apr_os_proc_mutex_get	(	apr_os_proc_mutex_t *	ospmutex,
		apr_proc_mutex_t *	pmutex
	)

Convert the proc mutex from os specific type to apr type

Parameters

ospmutex	The os specific proc mutex we are converting to.
pmutex	The apr proc mutex to convert.

apr_status_t apr_os_proc_mutex_put	(	apr_proc_mutex_t **	pmutex,
		apr_os_proc_mutex_t *	ospmutex,
		apr_pool_t *	cont
	)

Convert the proc mutex from os specific type to apr type

Parameters

pmutex	The apr proc mutex we are converting to.
ospmutex	The os specific proc mutex to convert.
cont	The pool to use if it is needed.

apr_status_t apr_os_shm_get	(	apr_os_shm_t *	osshm,
		apr_shm_t *	shm

convert the shm from apr type to os specific type.

Parameters

osshm	The os specific shm representation

Parameters

shm	The apr shm representation of osshm
osshm	The os specific shm identity
cont	The pool to use if it is needed.

Remarks

On fork()ed architectures, this is typically nothing more than the memory block mapped. On non-fork architectures, this is typically some internal handle to pass the mapping from process to process.

apr_status_t apr_os_sock_get	(	apr_os_sock_t *	thesock,
		apr_socket_t *	sock
	)

Convert the socket from an apr type to an OS specific socket

Parameters

thesock	The socket to convert.
sock	The os specific equivalent of the apr socket..

apr_status_t apr_os_sock_make	(	apr_socket_t **	apr_sock,
		apr_os_sock_info_t *	os_sock_info,
		apr_pool_t *	cont
	)

Create a socket from an existing descriptor and local and remote socket addresses.

Parameters

apr_sock	The new socket that has been set up
os_sock_info	The os representation of the socket handle and other characteristics of the socket
cont	The pool to use

Remarks

If you only know the descriptor/handle or if it isn't really a true socket, use apr_os_sock_put() instead.

apr_status_t apr_os_sock_put	(	apr_socket_t **	sock,
		apr_os_sock_t *	thesock,
		apr_pool_t *	cont
	)

Convert a socket from the os specific type to the apr type

Parameters

sock	The pool to use.
thesock	The socket to convert to.
cont	The socket we are converting to an apr type.

Remarks

If it is a true socket, it is best to call apr_os_sock_make() and provide APR with more information about the socket.
