Function avr_libc::strcmp_PF

pub unsafe extern "C" fn strcmp_PF(s1: *const i8, s2: uint_farptr_t) -> i16

\ingroup avr_pgmspace \fn int strcmp_PF(const char *s1, uint_farptr_t s2) \brief Compares two strings

The strcmp_PF() function is similar to strcmp() except that \e s2 is a far pointer to a string in program space.

\param s1 A pointer to the first string in SRAM \param s2 A far pointer to the second string in Flash

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