.SH DESCRIPTION
|
|
The
|
|
.BR strcasecmp
|
|
and
|
|
.BR strncasecmp
|
|
functions
|
|
compare the null-terminated strings
|
|
.I s1
|
|
and
|
|
.I s2
|
|
and return an integer greater than, equal to, or less than 0,
|
|
according as
|
|
.I s1
|
|
is lexicographically greater than, equal to, or less than
|
|
.I s2
|
|
after translation of each corresponding character to lower-case.
|
|
The strings themselves are not modified.
|
|
The comparison is done using unsigned characters, so that
|
|
.BR \e200
|
|
is greater than
|
|
.BR \e0 .
|
|
.LP
|
|
The
|
|
.BR strncasecmp
|
|
compares at most
|
|
.I len
|
|
characters.
|
|
.LP
|
|
.BR stricmp
|
|
and
|
|
.BR strincmp
|
|
are functionally identically equal to, and implemented in terms of,
|
|
.BR strcasecmp
|
|
and
|
|
.BR strncasecmp ,
|
|
respectively.
