hex.print_ptr_text

Prints len[:w/4] bytes from the pointed buffer.

Signature

def print_ptr_text ptr, len @ loop, finish, pptr, cnt, bytebuf, end { ... }

Defined in hex/strings.fj — lines 33–50 (view on GitHub).

Complexity

• Time: len(w(@+5) + 21@+27)

• Space: w(3@+55) + 16@+179

See the complexity glossary for what @, w, dw, dbit, n mean.

Requires init

The following must be initialised before this macro is invoked:

• hex.init and stl.ptr_init (or stl.startup_and_init_all).
