.TH curl_strequal 3 "30 April 2004" "libcurl" "libcurl"
.SH NAME
curl_strequal, curl_strnequal - case insensitive string comparisons
.SH SYNOPSIS
.nf
#include <curl/curl.h>

int curl_strequal(char *str1, char *str2);
int curl_strnequal(char *str1, char *str2, size_t length);
.fi
.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 \fIlength\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 EXAMPLE
.nf
if(curl_strequal(name, input))
  printf("Name and input matches\\n");
if(curl_strnequal(name, input, 5))
  printf("Name and input matches in the 5 first bytes\\n");
.fi
.SH AVAILABILITY
Always
.SH RETURN VALUE
Non-zero if the strings are identical. Zero if they are not.
.SH "SEE ALSO"
.BR strcmp "(3), " strcasecmp "(3)"
