.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.
|
|

|
|
.BR strcmp "(3), " strcasecmp "(3)"
