.SH NAME
strcasecmp, strncasecmp \- compare two strings ignoring case
.SH SYNOPSIS
@ -75,6 +75,20 @@ less than, to match, or be greater than
.IR s2 .
.SH CONFORMING TO
4.4BSD, POSIX.1-2001.
.SH NOTES
The
.BR strcasecmp ()
and
.BR strncasecmp ()
functions first appeared in 4.4BSD, where they were declared in
.IR <string.h> .
Thus, for reasons of historical compatibility, the glibc
.I <string.h>
header file also declares these functions, if the
.B _DEFAULT_SOURCE
(or, in glibc 2.19 and earlier,
.BR _BSD_SOURCE )
feature test macro is defined.
