Function avr_libc::strnlen_P

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

\ingroup avr_pgmspace \fn size_t strnlen_P(const char *src, size_t len) \brief Determine the length of a fixed-size string.

The strnlen_P() function is similar to strnlen(), except that \c src is a pointer to a string in program space.

\returns The strnlen_P function returns strlen_P(src), if that is less than \c len, or \c len if there is no '\0' character among the first \c len characters pointed to by \c src.
