<H2>DESCRIPTION</H2>
|
|
|
|
The
|
|
<B>strsignal</B>()
|
|
|
|
function returns a string describing the signal
|
|
number passed in the argument
|
|
<I>sig</I>.
|
|
|
|
The string can be used only until the next call to
|
|
<B>strsignal</B>().
|
|
|
|
<P>
|
|
|
|
The array
|
|
<I>sys_siglist</I>
|
|
|
|
holds the signal description strings
|
|
indexed by signal number.
|
|
The
|
|
<B>strsignal</B>()
|
|
|
|
function should be
|
|
used if possible instead of this array.
|
|
<A NAME="lbAE"> </A>
|
|
<H2>RETURN VALUE</H2>
|
|
|
|
The
|
|
<B>strsignal</B>()
|
|
|
|
function returns the appropriate description
|
|
string, or an unknown signal message if the signal number is invalid.
|
|
On some systems (but not on Linux), NULL may instead be
|
|
returned for an invalid signal number.
