Function avr_libc::strcmp_P

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

\ingroup avr_pgmspace \fn int strcmp_P(const char *s1, const char *s2)

The strcmp_P() function is similar to strcmp() except that \p s2 is pointer to a string in program space.

\returns The strcmp_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 strcmp_P() is that if \p s1 is an initial substring of \p s2, then \p s1 is considered to be "less than" \p s2.
