int strcoll ( const char * str1, const char * str2 );
Compare two strings using locale
Compares the C string str1 to the C string str2, both interpreted appropriately according to the LC_COLLATE category of the C locale currently selected.

This function starts comparing the first character of each string. If they are equal to each other continues with the following pair until the characters differ or until a null-character signaling the end of a string is reached.

The behavior of this function depends on the LC_COLLATE category of the selected C locale.
