sigqueue
SIGQUEUE(2) Linux Programmer's Manual SIGQUEUE(2)NAME
sigqueue - queue a signal and data to a process
SYNOPSIS
#include <signal.h>
int sigqueue(pid_t pid, int sig, const union sigval value);
DESCRIPTION
sigqueue() sends the signal specified in sig to the process whose PID is given in pid. The permissions required to send a signal are the
same as for kill(2). As with kill(2), the null signal (0) can be used to check if a process with a given PID exists.
The value argument is used to specify an accompanying item of data (either an integer or a pointer value) to be sent with the signal, and
has the following type:
union sigval {
int sival_int;
void *sival_ptr;
};
If the receiving process has installed a handler for this signal using the SA_SIGINFO flag to sigaction(2), then it can obtain this data
via the si_value field of the siginfo_t structure passed as the second argument to the handler. Furthermore, the si_code field of that
structure will be set to SI_QUEUE.
RETURN VALUE
On success, sigqueue() returns 0, indicating that the signal was successfully queued to the receiving proces. Otherwise -1 is returned and
errno is set to indicate the error.
ERRORS
EAGAIN The limit of signals which may be queued has been reached. (See signal(7) for further information.)
EINVAL sig was invalid.
ESRCH No process has a PID matching pid.
EPERM The process does not have permission to send the signal to the receiving process. (See kill(2) for further information.)
NOTES
If this function results in the sending of a signal to the process that invoked it, and that signal was not blocked by the calling thread,
and no other threads were willing to handle this signal (either by having it unblocked, or by waiting for it using sigwait(3)), then at
least some signal must be delivered to this thread before this function returns.
