[Help-glpk] Option to set to generate all solutions

[jordan]

Hi,
I'm actually using GLPK and I want to know if it is possible to set an
option in the source code for the C API, or in the file for a GMPL file,
in order to say "I want all the solutions".
I heard about re-lunch the programm with adding a constraint which is
the last solution, but I don't think it's a good thing.
Does somebody have the answer ?

PS : Sorry for English, I'm a french student.
