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.

ERRORS

%f3GL_INVALID_ENUMfP is generated if f2pnamefP is not an accepted value. %f3GL_INVALID_OPERATIONfP is generated if %f3glGetfP is executed between the execution of %f3glBeginfP and the corresponding execution of %f3glEndfP.
