Manual
Q_WAIT
NAMELIBRARY
SYNOPSIS
DESCRIPTION
RETURN VALUE
ERRORS
SEE ALSO
NAME
q_wait - return the next job from the queue, when available
LIBRARY
Librecast library ( liblibrecast , -llibrecast )
SYNOPSIS
#include <librecast/q.h>
int
q_wait(q_t
*q
, q_job_t
*job
);
int q_trywait(q_t
*q
, q_job_t
*job
);
Compile and link with -llibrecast .
DESCRIPTION
q_wait () atomically fetches the next job in q and sets the job pointer to it. The call blocks until a job is available.
q_trywait () is the same as q_wait () except that if the queue read lock cannot be immediately obtained, then the call returns an error ( errno set to EAGAIN ) instead of blocking.
RETURN VALUE
The q_push () function returns zero on success. On error, -1 is returned and errno is set to indicate the error.
ERRORS
The function can also fail with the errors for sem_post (3) or sem_wait (3).
