.SH NAME
|
|
curl_strequal, curl_strnequal \- case insensitive string comparisons
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
int curl_strequal(const char *str1, const char *str2);
|
|
int curl_strnequal(const char *str1, const char *str2, size_t length);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
The \fIcurl_strequal(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.
|
|
|
|
The \fBcurl_strnequal()\fP function is similar, except it only compares the
|
|
first \fIlength\fP characters of \fIstr1\fP.
|
|
|
|
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.
