How Does One Call An Existing PDB Procedure From A C Plug-in?

How do I access existing PDB procedures from a C plug-in? I'm very familiar with how this is done in Scheme & Python. I'm confused on how this is accomplished in C.

Can someone explain how this is done and/or provide a link to an example of a C plug-in that calls an existing procedure in the PDB?

Many Thanks!

Look for "gimp_run_procedure".

One example is in file-ico.c:

return_vals = gimp_run_procedure ("plug-in-threshold-alpha", &n_return_vals, GIMP_PDB_INT32, GIMP_RUN_NONINTERACTIVE, GIMP_PDB_IMAGE, tmp_image, GIMP_PDB_DRAWABLE, tmp_layer, GIMP_PDB_INT32, ICO_ALPHA_THRESHOLD, GIMP_PDB_END); gimp_destroy_params (return_vals, n_return_vals);

I hope this helps.

Bye, Simon
