C SPECIFICATION

void glGetMinmaxParameterfv( GLenum target,


                               GLenum pname,
                               GLfloat *params )

void glGetMinmaxParameteriv( GLenum target,


                               GLenum pname,
                               GLint *params )

PARAMETERS

target: Must be GL_MINMAX.
pname: The parameter to be retrieved. Must be one of GL_MINMAX_FORMAT or GL_MINMAX_SINK.
params: A pointer to storage for the retrieved parameters.

DESCRIPTION

glGetMinmaxParameter retrieves parameters for the current minmax table by setting pname to one of the following values:


Parameter	Description

GL_MINMAX_FORMAT	Internal of minmax table
GL_MINMAX_SINK	Value of the sink parameter

NOTES

glGetMinmaxParameter is present only if GL_ARB_imaging is returned when glGetString is called with an argument of GL_EXTENSIONS.

ERRORS

GL_INVALID_ENUM is generated if target is not GL_MINMAX.

GL_INVALID_ENUM is generated if pname is not one of the allowable values.

GL_INVALID_OPERATION is generated if glGetMinmaxParameter is executed between the execution of glBegin and the corresponding execution of glEnd.
