/*
|
Input used to generate the Python module "glmodule.c".
|
The stub generator is a Python script called "cgen.py".
|
|
Each definition must be contained on one line:
|
|
<returntype> <name> <type> <arg> <type> <arg>
|
|
<returntype> can be: void, short, long (XXX maybe others?)
|
|
<type> can be: char, string, short, float, long, or double
|
string indicates a null terminated string;
|
if <type> is char and <arg> begins with a *, the * is stripped
|
and <type> is changed into string
|
|
<arg> has the form <mode> or <mode>[<subscript>]
|
where <mode> can be
|
s: arg is sent
|
r: arg is received (arg is a pointer)
|
and <subscript> can be (N and I are numbers):
|
N
|
argI
|
retval
|
N*argI
|
N*I
|
N*retval
|
In the case where the subscript consists of two parts
|
separated by *, the first part is the width of the matrix, and
|
the second part is the length of the matrix. This order is
|
opposite from the order used in C to declare a two-dimensional
|
matrix.
