How to Call Awk from "C" with Libmawk

Libmawk is a fork of mawk 1.3.3 restructured for embedding. This means the user gets libmawk.h and libmawk.so and can embed awk scripting language in any application written in C.

the project can be downloaded here.

Features

Libmawk has the following main features:

  • load and run multiple awk scripts independently, in parallel
  • scripts do not read stdin but a memory buffer the embedding process can fill from time to time
  • running scripts in (mostly) non-blocking manner - that is, the script will not block if the process can not provide new input
  • all these without threads or fork()
  • call awk functions from C, using vararg for smooth integration
  • call C functions from awk scripts
  • resolve existing awk variables from C - read or write variables

License

Since mawk is licensed under the GNU GPL v2 and libmawk is a fork of mawk, libmawk is licensed under the GNU GPL v2 too.
