.SH 説明
The \fBstrsignal\fP()  function returns a string describing the signal number
passed in the argument \fIsig\fP.  The string can be used only until the next
call to \fBstrsignal\fP().  The string returned by \fBstrsignal\fP()  is localized
according to the \fBLC_MESSAGES\fP category in the current locale.
.PP
The \fBsigdescr_np\fP()  function returns a string describing the signal number
passed in the argument \fIsig\fP.  Unlike \fBstrsignal\fP()  this string is not
influenced by the current locale.
.PP
The \fBsigabbrev_np\fP()  function returns the abbreviated name of the signal,
\fIsig\fP.  For example, given the value \fBSIGINT\fP, it returns the string
"INT".
.PP
The (deprecated) array \fIsys_siglist\fP holds the signal description strings
indexed by signal number.  The \fBstrsignal\fP()  or the \fBsigdescr_np\fP()
function should be used instead of this array; see also VERSIONS.
.SH 返り値
\fBstrsignal\fP()  関数は、シグナルの適切な説明を返す。 もしシグナル番号が不正な場合は、未知のシグナル (unknown signal)
を示す メッセージを返す。 (Linux はそうではないが)不正なシグナル番号に対して、 NULL を返すシステムもある。
.PP
The \fBsigdescr_np\fP()  and \fBsigdabbrev_np\fP()  functions return the
appropriate description string.  The returned string is statically allocated
and valid for the lifetime of the program.  These functions return NULL for
an invalid signal number.
.SH バージョン
\fBsigdescr_np\fP() と \fBsigdabbrev_np\fP() は glibc 2.32 で初めて登場した。
.PP
.\" glibc commit b1ccfc061feee9ce616444ded8e1cd5acf9fa97f
Starting with version 2.32, the \fIsys_siglist\fP symbol is no longer exported
by glibc.
