PARAMETERS
- f2pnamefP
-
Specifies the parameter value to be returned.
The symbolic constants in the list below are accepted.
- f2paramsfP
-
Returns the value or values of the specified parameter.
DESCRIPTION
These four commands return values for simple state variables in GL.
f2pnamefP is a symbolic constant indicating the state variable to be returned,
and f2paramsfP is a pointer to an array of the indicated type in
which to place the returned data.
Type conversion is performed if f2paramsfP has a different type than
the state variable value being requested.
If %f3glGetBooleanvfP is called,
a floating-point (or integer) value is converted to %f3GL_FALSEfP if
and only if it is 0.0 (or 0).
Otherwise,
it is converted to %f3GL_TRUEfP.
If %f3glGetIntegervfP is called, boolean values are returned as
%f3GL_TRUEfP or %f3GL_FALSEfP, and most floating-point values are
rounded to the nearest integer value. Floating-point colors and
normals, however, are returned with a linear mapping that maps 1.0 to
the most positive representable integer value,
and -1.0 to the most negative representable integer value.
If %f3glGetFloatvfP or %f3glGetDoublevfP is called,
boolean values are returned as %f3GL_TRUEfP or %f3GL_FALSEfP,
and integer values are converted to floating-point values.
