NAME

pthread_condattr_init, pthread_condattr_destroy, — condition attribute operations

SYNOPSIS

#include <pthread.h>

int
pthread_condattr_init(pthread_condattr_t *attr);

int
pthread_condattr_destroy(pthread_condattr_t *attr);

DESCRIPTION

Condition attribute objects are used to specify parameters to pthread_cond_init(). FreeBSD's implementation of conditions does not support any non-default attributes, so these functions are not very useful, 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.

STANDARDS

The pthread_condattr_init() and pthread_condattr_destroy() functions conform to ISO/IEC 9945-1:1996 (“POSIX.1”)
