pthread_cond_init – create a condition variable

LIBRARY SYNOPSIS DESCRIPTION RETURN VALUES ERRORS SEE ALSO STANDARDS

POSIX Threads Library (libpthread, -lpthread)

#include <pthread.h>

int
pthread_cond_init(pthread_cond_t *restrict cond, const pthread_condattr_t *restrict attr);

The pthread_cond_init() function creates a new condition variable, with attributes specified with attr. If attr is NULL the default attributes are used.

If successful, the pthread_cond_init() function will return zero and put the new condition variable id into cond, otherwise an error number will be returned to indicate the error.

The pthread_cond_init() function will fail if:

[EINVAL]
	The value specified by attr is invalid.
[ENOMEM]
	The process cannot allocate enough memory to create another condition variable.
[EAGAIN]
	The system temporarily lacks the resources to create another condition variable.

The pthread_cond_init() function conforms to IEEE Std 1003.1-96 ("POSIX.1").
