psignal, sys_siglist, sys_signame -- system signal messages
Standard C Library (libc, -lc)
psignal(unsigned sig, const char *s);
extern const char * const sys_siglist;
extern const char * const sys_signame;
The psignal() function locates the descriptive message string for the
given signal number sig and writes it to the standard error.
If the argument s is non-NULL it 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 using the external array
sys_siglist, indexed by recognized signal numbers. The external array
sys_signame is used similarly and contains short, upper-case abbrevia-
tions 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), setlocale(3), strsignal(3)
The psignal() function appeared in 4.2BSD.
