Function avr_libc::memrchr_P

pub unsafe extern "C" fn memrchr_P(
    arg1: *const c_void, 
    __val: i16, 
    __len: size_t
) -> *const c_void

\ingroup avr_pgmspace \fn const void +memrchr_P(const void *src, int val, size_t len)

The memrchr_P() function is like the memchr_P() function, except that it searches backwards from the end of the \p len bytes pointed to by \p src instead of forwards from the front. (Glibc, GNU extension.)

\return The memrchr_P() function returns a pointer to the matching byte or \c NULL if the character does not occur in the given memory area.
