vacall - C functions called with variable arguments
This library allows C functions to be called with variable arguments and
to return variable return values. This is much like the varargs(3) facility,
but also allows the return value to be specified at run time.
A typical use is the implementation of call-back functions in embedded
interpreters.
Installation instructions:
Configure the parent directory. Then:
cd vacall
make
make check
make install
Files in this package:
Documentation:
README this text
COPYING free software license
PLATFORMS list of supported platforms
vacall.3 manual page in Unix man format
vacall.man manual page
vacall.html manual page in HTML format
Source:
vacall.h main include file
vacall-*.c source for the main interface function
vacall-*.[sS] its translation to assembly language
vacall-libapi.c implementation of other library API
vacall-structcpy.c auxiliary function
tests.c test program
Building:
Makefile.in Makefile master
Porting:
Makefile.devel developer's Makefile
This subdirectory produces a static library. Reason:
The vacall-*.c files access global variables. Such accesses causes
portability problems when combined with the option -fPIC (because of
the small/medium/large memory models and platform dependent assembler
syntax to access the GOT).
Therefore Makefile.devel in this directory compiles the files without -fPIC.
Therefore the resulting object files are not suitable for being put into
a shared library.
Therefore this direcory must
- either not use libtool,
- or pass '-static' to $(LIBTOOL_LINK) when creating libvacall.la.
