int curl_strenqual(char *str1, char *str2, size_t len);
function compares the two strings str1 and str2, ignoring the case
of the characters. It returns a non-zero (TRUE) integer if the strings are
The curl_strnequal() function is similar, except it only compares the
first len characters of str1.
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.
These functions will be removed from the public libcurl API in a near
future. They will instead be made "available" by source code access only, and
then as curlx_strequal() and curlx_strenqual().
Non-zero if the strings are identical. Zero if they're not.
