.SH DESCRIPTION
|
|
.LP
|
|
The \fIstrcasecmp\fP() function shall compare, while ignoring differences
|
|
in case, the string pointed to by \fIs1\fP to the
|
|
string pointed to by \fIs2\fP. The \fIstrncasecmp\fP() function shall
|
|
compare, while ignoring differences in case, not more than
|
|
\fIn\fP bytes from the string pointed to by \fIs1\fP to the string
|
|
pointed to by \fIs2\fP.
|
|
.LP
|
|
In the POSIX locale, \fIstrcasecmp\fP() and \fIstrncasecmp\fP() shall
|
|
behave as if the strings had been converted to lowercase
|
|
and then a byte comparison performed. The results are unspecified
|
|
in other locales.
|
|
.SH RETURN VALUE
|
|
.LP
|
|
Upon completion, \fIstrcasecmp\fP() shall return an integer greater
|
|
than, equal to, or less than 0, if the string pointed to by
|
|
\fIs1\fP is, ignoring case, greater than, equal to, or less than the
|
|
string pointed to by \fIs2\fP, respectively.
|
|
.LP
|
|
Upon successful completion, \fIstrncasecmp\fP() shall return an integer
|
|
greater than, equal to, or less than 0, if the possibly
|
|
null-terminated array pointed to by \fIs1\fP is, ignoring case, greater
|
|
than, equal to, or less than the possibly null-terminated
|
|
array pointed to by \fIs2\fP, respectively.
