getopt()

[RENAULT%HGRRUG5.BITNET at wiscvm.ARPA]

Dear reader(s),

I received a large C-program.
Every piece of software was present except one.
That is the function getopt(...).
I would be pleased if someone knew the function, has a detailed description
of it, has the source of that particulair routine or knows where to find
more information about it.

                Hoping someone will/can help me,
