Synopsis

#include <pthread.h> +

int pthread_condattr_init(pthread_condattr_t *attr); +

int pthread_condattr_destroy(pthread_condattr_t *attr); +

Description

Condition attributes can be specified at condition creation time, +by passing a condition attribute object as second argument to +pthread_cond_init(3) . +Passing NULL is equivalent to passing a condition attribute +object with all attributes set to their default values. +

pthread_condattr_init initializes the condition attribute +object attr and fills it with default values for the +attributes. pthread_condattr_destroy destroys a condition +attribute object, which must not be reused until it is reinitialized.

Pthreads-w32 defines _POSIX_THREAD_PROCESS_SHARED in +pthread.h as -1 to indicate that the attribute routines are +implemented but that the process shared attribute is not supported.

Return Value

All condition variable functions return 0 on success and a +non-zero error code on error.

Errors

The pthread_condattr_init function returns the following +error code on error: +

ENOMEM +: + The was insufficient memory to create the attribute. + +

+ +

+The pthread_condattr_destroy function returns the following +error code on error: +

EINVAL +: + The attr argument is not valid. + +
