.SH NAME
curl_strnequal \- compare two strings ignoring case
.SH SYNOPSIS
.nf
#include <curl/curl.h>
int curl_strnequal(const char *str1, const char *str2, size_t length);
.fi
.SH DESCRIPTION
The \fIcurl_strnequal(3)\fP 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.
This function compares no more than the first \fIlength\fP bytes of \fIstr1\fP and
\fIstr2\fP.
This function uses plain ASCII based comparisons completely disregarding the
locale \- contrary to how \fBstrcasecmp\fP and other system case insensitive
string comparisons usually work.
This function is provided by libcurl to enable applications to compare strings
in a truly portable manner. There are no standard portable case insensitive
string comparison functions. This function works on all platforms.
.SH PROTOCOLS
This functionality affects all supported protocols
.SH EXAMPLE
.nf
int main(int argc, char **argv)
{
const char *name = "compare";
if(curl_strnequal(name, argv[1], 5))
printf("Name and input matches in the 5 first bytes\\n");
}
.fi
.SH AVAILABILITY
Added in curl 7.1
.SH RETURN VALUE
Non\-zero if the strings are identical. Zero if they are not.
