# GB.toupper

int GB.toupper ( int c )

This is a locale insensitive replacement for the glibc `toupper()` function.

You must use this function instead of the standard glibc one to compare ASCII strings in a case unsensitive way, because the glibc one is localization aware.

And if you did not know yet, in turkish, `strcasecmp("i", "I") != 0`.
