PTHREAD_COND_INIT(3)     BSD Library Functions Manual     PTHREAD_COND_INIT(3)

     pthread_cond_init -- create a condition variable

     #include <pthread.h>

     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.

     pthread_cond_init() will fail if:

     [EAGAIN]           The system temporarily lacks the resources to create another condition variable.

     [EINVAL]           The value specified by attr is invalid.

     [ENOMEM]           The process cannot allocate enough memory to create another condition variable.

     pthread_cond_broadcast(3), pthread_cond_destroy(3), pthread_cond_signal(3), pthread_cond_timedwait(3),

     pthread_cond_init() conforms to ISO/IEC 9945-1:1996 (``POSIX.1'').
