psignal -- print signal message


#include <signal.h>

void psignal(int sig, const char * s);

extern const char *const sys_siglist[]


The psignal() function shall display a message on the stderr stream. If s is not the null pointer, and does not point to an empty string (e.g. "\0"), the message shall consist of the string s, a colon, a space, and a string describing the signal number sig; otherwise psignal() shall display only a message describing the signal number sig. If sig is invalid, the message displayed shall indicate an unknown signal.

The array sys_siglist holds the signal description strings indexed by signal number.
