NAME
     pthread_cond_init - create a condition variable

LIBRARY
     POSIX Threads Library (libpthread, -lpthread)

SYNOPSIS
     #include <pthread.h>

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

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

RETURN VALUES
     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.

ERRORS
     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.
