PARAMETERS

_p_n_a_m_e
Specifies the parameter value to be returned. The symbolic constants in the list below are accepted.
_p_a_r_a_m_s
Returns the value or values of the specified parameter.

DESCRIPTION

These four commands return values for simple state variables in GL. _p_n_a_m_e is a symbolic constant indicating the state variable to be returned, and _p_a_r_a_m_s is a pointer to an array of the indicated type in which to place the returned data.

Type conversion is performed if _p_a_r_a_m_s has a different type than the state variable value being requested. If ggllGGeettBBoooolleeaannvv is called, a floating-point (or integer) value is converted to GGLL__FFAALLSSEE if and only if it is 0.0 (or 0). Otherwise, it is converted to GGLL__TTRRUUEE. If ggllGGeettIInntteeggeerrvv is called, boolean values are returned as GGLL__TTRRUUEE or GGLL__FFAALLSSEE, 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 ggllGGeettFFllooaattvv or ggllGGeettDDoouubblleevv is called, boolean values are returned as GGLL__TTRRUUEE or GGLL__FFAALLSSEE, and integer values are converted to floating-point values.
