glGetMinmaxParameter — get minmax parameters
void glGetMinmaxParameterfv( | GLenum | target, |
GLenum | pname, | |
GLfloat * | params) ; |
void glGetMinmaxParameteriv( | GLenum | target, |
GLenum | pname, | |
GLint * | params) ; |
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.
glGetMinmaxParameter
retrieves parameters for the current minmax table by setting
pname
to one of the following values:
Parameter | Description |
---|---|
GL_MINMAX_FORMAT
| Internal format of minmax table |
GL_MINMAX_SINK
| Value of the sink parameter |
glGetMinmaxParameter
is present only if ARB_imaging
is returned when glGetString
is called with an argument of GL_EXTENSIONS
.
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.
