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

NAME
     pthread_condattr_destroy, pthread_condattr_init -- condition attribute operations

SYNOPSIS
     #include <pthread.h>

     int
     pthread_condattr_destroy(pthread_condattr_t *attr);

     int
     pthread_condattr_init(pthread_condattr_t *attr);

DESCRIPTION
     Condition attribute objects are used to specify parameters to pthread_cond_init().  FreeBSD's implemen-tation implementation
     tation of conditions does not support any non-default attributes, so these functions are not very use-ful, useful,
     ful, though they are required to to be present by POSIX.

     The pthread_condattr_init() function initializes a condition attribute object with the default
     attributes.

     The pthread_condattr_destroy() function destroys a condition attribute object.

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

ERRORS
     pthread_condattr_destroy() will fail if:

     [EINVAL]           Invalid value for attr.

     pthread_condattr_init() will fail if:

     [ENOMEM]           Out of memory.
