typedef int apr_signum_t

Enumerations

enum  apr_wait_type_t { APR_WAIT_READ, APR_WAIT_WRITE }

Detailed Description

This is collection of oddballs that didn't fit anywhere else, and might move to more appropriate headers with the release of APR 1.0.


Define Documentation

#define APR_ALIGN (   size,
  boundary 
)    (((size) + ((boundary) - 1)) & ~((boundary) - 1))

Alignment macros

#define APR_ALIGN_DEFAULT (   size)    APR_ALIGN(size, 8)

Default alignment

#define APR_ASCII_BLANK   '\040'

a space

#define APR_ASCII_CR   '\015'

a carrige return

#define APR_ASCII_LF   '\012'

#define APR_ASCII_TAB   '\011'

a tab

#define APR_OFFSET (   p_type,
  field 
)    ((long) (((char *) (&(((p_type)NULL)->field))) - ((char *) NULL)))

Finding offsets of elements within structures. Taken from the X code... they've sweated portability of this stuff so we don't have to. Sigh...

Parameters:
p_typepointer type name
fielddata field within the structure pointed to
Returns:
offset
#define APR_OFFSETOF (   s_type,
  field 
)    APR_OFFSET(s_type*,field)

Finding offsets of elements within structures.

Parameters:
s_typestructure type name
fielddata field within the structure
Returns:
offset
#define APR_STRINGIFY (   n)    APR_STRINGIFY_HELPER(n)

String and memory functions Properly quote a value as a string in the C preprocessor

#define APR_STRINGIFY_HELPER (   n)    #n

Helper macro for APR_STRINGIFY

#define APR_TYPEDEF_STRUCT (   type,
  incompletion 
)
Value:
struct type { \
   incompletion \
   void *unk[]; \
};

Macro to provide a way to turn an incomplete type into a complete type containing common pointers for a provider.

#define FALSE   0

FALSE

#define TRUE   (!FALSE)

TRUE
