• File ffcall/callback/vacall_r/README — part of check-in [24d3bc4776] at 2011-01-30 17:11:43 on branch trunk — Adding ffcall (and built files) (user: matt, size: 369) [annotate] [blame] [check-ins using]

This directory contains a reentrant version of the vacall package.

Instead of using a global variable for the function to be called,
a pointer is passed in a special CPU register, pointing to:
  - a function code pointer in the first word,
  - a data word in the second word, to be passed before the va_alist.

The include file <vacall.h> is renamed to <vacall_r.h>.
