Function avr_libc::strcasecmp_P

pub unsafe extern "C" fn strcasecmp_P(arg1: *const i8, arg2: *const i8) -> i16

\ingroup avr_pgmspace \fn int strcasecmp_P(const char *s1, const char *s2) \brief Compare two strings ignoring case.

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

\param s1 A pointer to a string in the devices SRAM. \param s2 A pointer to a string in the devices Flash.

\returns The strcasecmp_P() function returns an integer less than, equal to, or greater than zero if \p s1 is found, respectively, to be less than, to match, or be greater than \p s2. A consequence of the ordering used by strcasecmp_P() is that if \p s1 is an initial substring of \p s2, then \p s1 is considered to be "less than" \p s2.
