Function avr_libc::strlcat_PF

pub unsafe extern "C" fn strlcat_PF(
    dst: *mut i8, 
    src: uint_farptr_t, 
    siz: size_t
) -> size_t

\ingroup avr_pgmspace \fn size_t strlcat_PF(char *dst, uint_farptr_t src, size_t n) \brief Concatenate two strings

The strlcat_PF() function is similar to strlcat(), except that the \e src string must be located in program space (flash) and is addressed using a far pointer.

Appends src to string dst of size \e n (unlike strncat(), \e n is the full size of \e dst, not space left). At most \e n-1 characters will be copied. Always NULL terminates (unless \e n <= strlen(\e dst)).

\param dst A pointer to the destination string in SRAM \param src A far pointer to the source string in Flash \param n The total number of bytes allocated to the destination string

\returns The strlcat_PF() function returns strlen(\e src) + MIN(\e n, strlen(initial \e dst)). If retval >= \e n, truncation occurred. The contents of RAMPZ SFR are undefined when the funcion returns.
