DESCRIPTION¶ sigsuspend() temporarily replaces the signal mask of the calling process with the mask given by mask and then suspends the process until delivery of a signal whose action is to invoke a signal handler or to terminate a process. The mask remains set only as long as sigsuspend is waiting. The sigsuspend() function replaces the caller&39;s signal mask with the set of signals pointed to by the set argument and suspends the caller until delivery of a signal whose action is either to execute a signal catching function or to terminate the process.

This function is supported only in a POSIX program. For more information about the manual page format, see the manual page for manpages(5). sigsuspend() suspends only the calling thread until it receives a signal. Normally, sigsuspend() is used in conjunction with sigprocmask(2) in order to prevent delivery of a signal during the execution of a critical code section.

SIGSUSPEND Section: Linux Programmer&39;s Manual (2) Updated:Index Return to Main Contents NAME sigsuspend - wait for a signal SYNOPSIS include Function: int sigsuspend (const sigset_t *set). La descripción del manual de GNU libc parece clara y completa: Función: int sigsuspend (const sigset_t * set) Esta función reemplaza la máscara de señal del proceso con set y luego suspende el proceso hasta que se entrega una señal cuya acción es terminar el proceso o invocar una sigsuspend manual función de manejo de señal. sigsuspend() temporarily changes the blocked signal mask to the set to which sigmask points, and then waits for a signal to arrive; on return the previous set of masked signals is restored.

h> int pause ( void ); DESCRIPTION Pause is made obsolete by sigsuspend(2). The return value and error conditions are the same as for pause. The pause() function shall suspend the calling thread until delivery of a signal whose action is either to execute a signal-catching func- tion or to terminate the process. The function sigpause() is designed to wait for some signal. Are SIGCHLD signal and its handler used only in asychronous manner: the process which installs a handler for SIGCHLD goes on to do something else. DESCRIPTION¶ sigsuspend() temporarily replaces the signal mask of the calling thread with the mask given by mask and then suspends the thread until delivery of a signal whose action is to invoke a signal handler or to terminate a process. Description sigsuspend () temporarily replaces the signal mask of the calling process with the mask given by mask and then suspends the process until delivery of a signal whose action is to invoke a signal handler or to terminate a process. However, on return to the calling process, the signal mask is restored to the value it had before the call to the sigsuspend function.

DESCRIPTION sigsuspend () temporarily replaces the signal mask of the calling process with the mask given by mask and then suspends the process until delivery of a signal whose action is to invoke a signal handler or to terminate a process. sigsuspend(): _POSIX_C_SOURCE. For this reason, the use of sigwait(2) is recommended instead of sigsuspend() for multi-threaded.

The function sigsuspend always restores the previous signal mask when it returns. rt_sigsuspend(2) sigtimedwait(2) rt_sigtimedwait(2) If a signal handler is invoked while a system call or library function call is. sigsuspend() temporarily replaces the signal mask of the calling thread with the mask given by mask and then suspends the thread until delivery of a signal whose action is to invoke a signal handler or to terminate a process.

The sigsuspend() function shall replace the current signal mask of the calling thread with the set of signals pointed to by sigmask and then suspend the thread until delivery of a signal whose action is either to execute a signal-catching function or to terminate the process. If the signal terminates the process, then sigsuspend () does not return. The sigsuspend call temporarily replaces the signal mask for the process with that given by mask and then suspends the process until a signal is received. The sigsuspend() function shall replace the current signal mask sigsuspend manual of the calling thread with the set of signals pointed to by sigmask and then suspend the thread until delivery of a signal whose action is either to execute a signal-. If an incoming signal is handled by a signal-handling function, sigsuspend() returns after the signal-handling function returns.
