glGetMap

glGetMapdv, glGetMapfv, glGetMapiv: return evaluator parameters.
C Specification
void glGetMapdv(
void glGet
void glGetMapiv(
Parameters
target
query
v
Description
glMap1 and glMap2 define evaluators. glGetMap returns evaluator parameters. target
chooses a map, query selects a specific parameter, and v points to storage where the
values will be returned.
The acceptable values for the target parameter are described in the glMap1 and glMap2
reference pages.
query can assume the following values:
GL_COEFF
v returns the control points for the evaluator function. One-dimensional evaluators
return order control points, and two-dimensional evaluators return uorder times vorder
control points. Each control point consists of one, two, three, or four integer,
single-precision floating-point, or double-precision floating-point values, depending on
