.TH curl_strequal 3 "November 05, 2020" "libcurl 7.77.0" "libcurl Manual"
.SH NAME
curl_strequal, curl_strnequal - case insensitive string comparisons
.SH SYNOPSIS
.B #include <curl/curl.h>
.sp
.BI "int curl_strequal(char *" str1 ", char *" str2 ");"
.sp
.BI "int curl_strnequal(char *" str1 ", char *" str2 ", size_t " len ");"
.SH DESCRIPTION
The
.B curl_strequal()
function compares the two strings \fIstr1\fP and \fIstr2\fP, ignoring the case
of the characters. It returns a non-zero (TRUE) integer if the strings are
identical.
.sp
The \fBcurl_strnequal()\fP function is similar, except it only compares the
first \fIlen\fP characters of \fIstr1\fP.
.sp
These functions are provided by libcurl to enable applications to compare
strings in a truly portable manner. There are no standard portable case
insensitive string comparison functions. These two work on all platforms.
.SH AVAILABILITY
These functions will be removed from the public libcurl API in a near
future. They will instead be made "available" by source code access only, and
then as curlx_strequal() and curlx_strenqual().
.SH RETURN VALUE
Non-zero if the strings are identical. Zero if they're not.
.SH "SEE ALSO"
.BR strcmp "(3), " strcasecmp "(3)"
