2.3.39 int strcasecmp_PF

int strcasecmp_PF(const char *s1, uint_farptr_t s2) __ATTR_PURE__

The strcasecmp_PF() function compares the two strings s1 and s2, ignoring the case of the characters.

Remember:

The strcasecmp_PF() function returns an integer less than, equal to, or greater than zero if s1 is found, respectively, to be less than, to match, or be greater than s2. The contents of RAMPZ SFR are undefined when the function returns.
