SYNOPSIS


.In signal.h void psignal unsigned sig const char *s
.Vt extern const char * const sys_siglist[] ;
.Vt extern const char * const sys_signame[] ;
.In string.h char * strsignal int sig

DESCRIPTION

The psignal and strsignal functions locate the descriptive message string for a signal number.

The strsignal function accepts a signal number argument sig and returns a pointer to the corresponding message string.

The psignal function accepts a signal number argument sig and writes it to the standard error. If the argument s is non- NULL and does not point to the null character, s is written to the standard error file descriptor prior to the message string, immediately followed by a colon and a space. If the signal number is not recognized (sigaction(2)), the string "Unknown signal" is produced.

The message strings can be accessed directly through the external array sys_siglist, indexed by recognized signal numbers. The external array sys_signame is used similarly and contains short, upper-case abbreviations for signals which are useful for recognizing signal names in user input. The defined variable NSIG contains a count of the strings in sys_siglist and sys_signame.

sigaction(2), perror(3), strerror(3)

HISTORY

The psignal function appeared in BSD 4.2 .
