-.SH NAME
-sigqueue \- queue a signal and data to a process
-.SH LIBRARY
-Standard C library
-.RI ( libc ", " \-lc )
-.SH SYNOPSIS
-.nf
-.B #include <signal.h>
-.P
-.BI "int sigqueue(pid_t " pid ", int " sig ", const union sigval " value );
-.fi

-.BR sigqueue ():
-.nf
-    _POSIX_C_SOURCE >= 199309L
-.fi
-.SH DESCRIPTION
-.BR sigqueue ()
-sends the signal specified in
-.I sig
-to the process whose PID is given in
-.IR pid .
-The permissions required to send a signal are the same as for
-.BR kill (2).
-As with
-.BR kill (2),
-the null signal (0) can be used to check if a process with a given
-PID exists.
-.P
-The
-.I 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:
-.P
-.in +4n
-.EX
-union sigval {
-    int   sival_int;
-    void *sival_ptr;
-};
-.EE
-.in
-.P
-If the receiving process has installed a handler for this signal using the
-.B SA_SIGINFO
-flag to
-.BR sigaction (2),
-then it can obtain this data via the
-.I si_value
-field of the
-.I siginfo_t
-structure passed as the second argument to the handler.
-Furthermore, the
-.I si_code
-field of that structure will be set to
-.BR SI_QUEUE .
-.SH RETURN VALUE
-On success,
-.BR sigqueue ()
-returns 0, indicating that the signal was successfully
-queued to the receiving process.
-Otherwise, \-1 is returned and
-.I errno
-is set to indicate the error.
-.SH ERRORS
-.TP
-.B EAGAIN
-The limit of signals which may be queued has been reached.
-(See
-.BR signal (7)
-for further information.)
-.TP
-.B EINVAL
-.I sig
-was invalid.
-.TP
-.B EPERM
-The process does not have permission to send the signal
-to the receiving process.
-For the required permissions, see
-.BR kill (2).
-.TP
-.B ESRCH
-No process has a PID matching
-.IR pid .
-.SH ATTRIBUTES
-For an explanation of the terms used in this section, see
-.BR attributes (7).

-.SH VERSIONS
-.SS C library/kernel differences
-On Linux,
-.BR sigqueue ()
-is implemented using the
-.BR rt_sigqueueinfo (2)
-system call.
-The system call differs in its third argument, which is the
-.I siginfo_t
-structure that will be supplied to the receiving process's
-signal handler or returned by the receiving process's
-.BR sigtimedwait (2)
-call.
-Inside the glibc
-.BR sigqueue ()
-wrapper, this argument,
-.IR uinfo ,
-is initialized as follows:
-.P
-.in +4n
-.EX
-uinfo.si_signo = sig;      /* Argument supplied to sigqueue() */
-uinfo.si_code = SI_QUEUE;
-uinfo.si_pid = getpid();   /* Process ID of sender */
-uinfo.si_uid = getuid();   /* Real UID of sender */
-uinfo.si_value = val;      /* Argument supplied to sigqueue() */
-.EE

-.SH STANDARDS
-POSIX.1-2008.
-.SH HISTORY
-Linux 2.2.
-POSIX.1-2001.
-.SH 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
-.BR sigwait (3)),
-then at least some signal must be delivered to this thread before this
-function returns.
