psignal—print a signal message on standard error #include <stdio.h>
void psignal(int signal, const char *prefix);
Description
Use psignal to print (on standard error) a signal message
corresponding to the value of the signal number signal.
Unless you use NULL as the value of the argument prefix, the
signal message will begin with the string at prefix, followed by a
colon and a space (: ). The remainder of the signal message is one
of the strings described for strsignal.
Returns
psignal returns no result.
Portability
POSIX.1-2008 requires psignal, but the strings issued vary from one
implementation to another.
Supporting OS subroutines required: close, fstat, isatty,
lseek, read, sbrk, write.
