PTHREAD_CONDATTR(3)					   BSD Library Functions Manual 				       PTHREAD_CONDATTR(3)

NAME

     pthread_condattr_init -- condition attribute operations

LIBRARY

     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS

     #include <pthread.h>

     int
     pthread_condattr_init(pthread_condattr_t *attr);

     int
     pthread_condattr_setclock(pthread_condattr_t *attr, clockid_t clock);

     int
     pthread_condattr_destroy(pthread_condattr_t *attr);

DESCRIPTION

     Condition attribute objects are used to specify parameters to the pthread_cond_init(3) function.  The pthread_condattr_init() function ini-
     tializes a condition attribute object with the default attributes and the pthread_condattr_destroy() function destroys a condition attribute
     object.  The pthread_condattr_setclock() function sets the system clock to be used for time comparisons to the one specified in clock.  Valid
     clock values are CLOCK_MONOTONIC and CLOCK_REALTIME (the default).

RETURN VALUES

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

ERRORS

     No errors are defined for pthread_condattr_init().

     The pthread_condattr_destroy() function may fail if:

     [EINVAL]		The value specified by attr is invalid.

SEE ALSO

     pthread_cond_init(3)

STANDARDS

     Both functions conform to IEEE Std 1003.1-2001 (``POSIX.1'').

CAVEATS

     The usefulness of the functions is questionable as the NetBSD implementation does not support any non-default attributes.	These functions do
     not conform to the IEEE Std 1003.1-2008 (``POSIX.1'') revision of the standard, which mandates two additional attributes, the clock attribute
     and the process-shared attribute.
