NAME

sigpending − Examines pending signals

SYNOPSIS

#include <signal.h> int sigpending (
sigset_t ∗set );

PARAMETERS

setPoints to a sigset_t structure. 

DESCRIPTION

The sigpending() function stores the set of signals that are blocked from delivery and pending to the calling process in the object pointed to by the set parameter. 

Applications should call either the sigemptyset() or the sigfillset() function at least once for each object of type sigset_t prior to any other use of that object. If such an object is not initialized in this way, but is nonetheless supplied as an argument to the sigpending() function, the results are undefined. 

NOTES

AES Support Level:
Full use

RETURN VALUES

Upon successful completion, the sigpending() function returns a value of 0 (zero).  Otherwise, a value of −1 is returned and errno is set to indicate the error. 

ERRORS

If a bad mask parameter is passed, the calling process receives a SIGSEGV signal.
