Detailed Description

Private Inlined Routines for POSIX Mutex's.

This include file contains the static inline implementation of the private inlined routines for POSIX mutex's.

Macro Definition Documentation

POSIX_MUTEX_VALIDATE_OBJECT

#define POSIX_MUTEX_VALIDATE_OBJECT	(		the_mutex,
			flags
	)

Value:

  do { \
    if ( ( the_mutex ) == NULL ) { \
      return EINVAL; \
    } \
    flags = ( the_mutex )->flags; \
    if ( \
      ( ( (uintptr_t) ( the_mutex ) ^ POSIX_MUTEX_MAGIC ) \
          & ~POSIX_MUTEX_FLAGS_MASK ) \
        != ( flags & ~POSIX_MUTEX_FLAGS_MASK ) \
    ) { \
      if ( !_POSIX_Mutex_Auto_initialization( the_mutex ) ) { \
        return EINVAL; \
      } \
    } \
  } while ( 0 )
