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. .SH PROTOCOLS All .SH EXAMPLE .nf int main(int argc, char **argv) { const char *name = "compare"; if(curl_strequal(name, argv[1])) printf("Name and input matches\\n"); if(curl_strnequal(name, argv[1], 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 strcasecmp (3), .BR strcmp (3)
