PTHREAD_MUTEXATTR(3)	 BSD Library Functions Manual	  PTHREAD_MUTEXATTR(3)

NAME
     pthread_mutexattr_init, pthread_mutexattr_destroy,
     pthread_mutexattr_setprioceiling, pthread_mutexattr_getprioceiling,
     pthread_mutexattr_setprotocol, pthread_mutexattr_getprotocol,
     pthread_mutexattr_settype, pthread_mutexattr_gettype — mutex attribute
     operations

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

     int
     pthread_mutexattr_init(pthread_mutexattr_t *attr);

     int
     pthread_mutexattr_destroy(pthread_mutexattr_t *attr);

     int
     pthread_mutexattr_setprioceiling(pthread_mutexattr_t *attr,
	 int prioceiling);

     int
     pthread_mutexattr_getprioceiling(pthread_mutexattr_t *attr,
	 int *prioceiling);

     int
     pthread_mutexattr_setprotocol(pthread_mutexattr_t *attr, int protocol);

     int
     pthread_mutexattr_getprotocol(pthread_mutexattr_t *attr, int *protocol);

     int
     pthread_mutexattr_settype(pthread_mutexattr_t *attr, int type);

     int
     pthread_mutexattr_gettype(pthread_mutexattr_t *attr, int *type);

DESCRIPTION
     Mutex attributes are used to specify parameters to pthread_mutex_init().
     One attribute object can be used in multiple calls to
     pthread_mutex_init(), with or without modifications between calls.

     The pthread_mutexattr_init() function initializes attr with all the
     default mutex attributes.

     The pthread_mutexattr_destroy() function destroys attr.

     The pthread_mutexattr_set*() functions set the attribute that corresponds
     to each function name.

     The pthread_mutexattr_get*() functions copy the value of the attribute
     that corresponds to each function name to the location pointed to by the
     second function parameter.

RETURN VALUES
     If successful, these functions return 0.  Otherwise, an error number is
     returned to indicate the error.

ERRORS
     The pthread_mutexattr_init() function will fail if:

     [ENOMEM]		Out of memory.

     The pthread_mutexattr_destroy() function will fail if:

     [EINVAL]		Invalid value for attr.

     The pthread_mutexattr_setprioceiling() function will fail if:

     [EINVAL]		Invalid value for attr, or invalid value for
			prioceiling.

     The pthread_mutexattr_getprioceiling() function will fail if:

     [EINVAL]		Invalid value for attr.

     The pthread_mutexattr_setprotocol() function will fail if:

     [EINVAL]		Invalid value for attr, or invalid value for protocol.

     The pthread_mutexattr_getprotocol() function will fail if:

     [EINVAL]		Invalid value for attr.

     The pthread_mutexattr_settype() function will fail if:

     [EINVAL]		Invalid value for attr, or invalid value for type.

     The pthread_mutexattr_gettype() function will fail if:

     [EINVAL]		Invalid value for attr.

SEE ALSO

STANDARDS
     The pthread_mutexattr_init() and pthread_mutexattr_destroy() functions
     conform to ISO/IEC 9945-1:1996 (“POSIX.1”)

     The pthread_mutexattr_setprioceiling(),
     pthread_mutexattr_getprioceiling(), pthread_mutexattr_setprotocol(),
     pthread_mutexattr_getprotocol(), pthread_mutexattr_settype(), and
     pthread_mutexattr_gettype() functions conform to Version 2 of the Single
     UNIX Specification (“SUSv2”)
