FUNCTION

	<>---convert signal number to string

INDEX

	strsignal

ANSI_SYNOPSIS

	#include 

	char *strsignal(int <[signal]>);

TRAD_SYNOPSIS

	#include 

	char *strsignal(<[signal]>)

	int <[signal]>;

DESCRIPTION

<> converts the signal number <[signal]> into a

string.  If <[signal]> is not a known signal number, the result

will be of the form "Unknown signal NN" where NN is the <[signal]>

is a decimal number.

RETURNS

This function returns a pointer to a string.  Your application must

not modify that string.

PORTABILITY

POSIX.1-2008 C requires <>, but does not specify the strings used

for each signal number.

<> requires no supporting OS subroutines.

QUICKREF

	strsignal pure
