22 .TH curl_strequal 3 "30 April 2004" "libcurl 7.12" "libcurl Manual"
23 .SH NAME
24 curl_strequal, curl_strnequal - case insensitive string comparisons
25 .SH SYNOPSIS
26 .B #include <curl/curl.h>
27 .sp
28 .BI "int curl_strequal(char *" str1 ", char *" str2 ");"
29 .sp
30 .BI "int curl_strnequal(char *" str1 ", char *" str2 ", size_t " len ");"
31 .SH DESCRIPTION
32 The
33 .B curl_strequal()
34 function compares the two strings \fIstr1\fP and \fIstr2\fP, ignoring the case
35 of the characters. It returns a non-zero (TRUE) integer if the strings are
36 identical.
37 .sp
38 The \fBcurl_strnequal()\fP function is similar, except it only compares the
39 first \fIlen\fP characters of \fIstr1\fP.
40 .sp
41 These functions are provided by libcurl to enable applications to compare
42 strings in a truly portable manner. There are no standard portable case
43 insensitive string comparison functions. These two work on all platforms.
44 .SH AVAILABILITY
45 These functions will be removed from the public libcurl API in a near
46 future. They will instead be made "available" by source code access only, and
47 then as curlx_strequal() and curlx_strenqual().
48 .SH RETURN VALUE
49 Non-zero if the strings are identical. Zero if they're not.
50 .SH "SEE ALSO"
51 .BR strcmp "(3), " strcasecmp "(3)"
