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)"
