ANSI_SYNOPSIS
|
||
|
|
#include <stdio.h>
|
||
|
|
void psignal(int <[signal]>, const char *<[prefix]>);
|
||
|
|
|
||
|
|
TRAD_SYNOPSIS
|
||
|
|
#include <stdio.h>
|
||
|
|
void psignal(<[signal]>, <[prefix]>)
|
||
|
|
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>>.
