`hex/strings.fj`¶

Line / byte-buffer helpers: read a whole line into a buffer and print buffers back. (By “buffers” we mean hex.pointers to those buffers.)

Macros¶

hex.input_ptr_line — Reads bytes from input into the pointed buffer, until a '\n' or a 0-byte (EOF); writes the byte count into len[:w/4].
hex.print_ptr_text — Prints len[:w/4] bytes from the pointed buffer.
hex.print_ptr_line — Prints bytes from the pointed buffer, until a '\n' or a 0-byte (EOF); writes the byte count into len[:w/4].
hex.fill_bytes — Fills “count[:w/4]” bytes of the pointed buffer with the value byte.
hex.copy_bytes — Copies “count[:w/4]” bytes from the src-pointed buffer to the dst-pointed buffer.
