Function avr_libc::memmem_P

pub unsafe extern "C" fn memmem_P(
    arg1: *const c_void, 
    arg2: size_t, 
    arg3: *const c_void, 
    arg4: size_t
) -> *mut c_void

\ingroup avr_pgmspace \fn void *memmem_P(const void *s1, size_t len1, const void *s2, size_t len2)

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