GLGETSTRING(3G) 						  [FIXME: manual]						   GLGETSTRING(3G)

NAME

       glGetString - return a string describing the current GL connection

C SPECIFICATION

       const GLubyte* glGetString(GLenum name);

C SPECIFICATION

       const GLubyte* glGetStringi(GLenum name, GLuint index);

PARAMETERS

       name
	   Specifies a symbolic constant, one of GL_VENDOR, GL_RENDERER, GL_VERSION, or GL_SHADING_LANGUAGE_VERSION. Additionally, glGetStringi
	   accepts the GL_EXTENSIONS token.

       index
	   For glGetStringi, specifies the index of the string to return.

DESCRIPTION

       glGetString returns a pointer to a static string describing some aspect of the current GL connection.  name can be one of the following:

       GL_VENDOR

	   Returns the company responsible for this GL implementation. This name does not change from release to release.

       GL_RENDERER

	   Returns the name of the renderer. This name is typically specific to a particular configuration of a hardware platform. It does not
	   change from release to release.

       GL_VERSION

	   Returns a version or release number.

       GL_SHADING_LANGUAGE_VERSION

	   Returns a version or release number for the shading language.

       glGetStringi returns a pointer to a static string indexed by index.  name can be one of the following:

       GL_EXTENSIONS

	   For glGetStringi only, returns the extension string supported by the implementation at index.

       Strings GL_VENDOR and GL_RENDERER together uniquely specify a platform. They do not change from release to release and should be used by
       platform-recognition algorithms.

       The GL_VERSION and GL_SHADING_LANGUAGE_VERSION strings begin with a version number. The version number uses one of these forms:

       major_number.minor_number major_number.minor_number.release_number

       Vendor-specific information may follow the version number. Its format depends on the implementation, but a space always separates the
       version number and the vendor-specific information.

       All strings are null-terminated.

NOTES

       If an error is generated, glGetString returns 0.

       The client and server may support different versions.  glGetString always returns a compatible version number. The release number always
       describes the server.

ERRORS

       GL_INVALID_ENUM is generated if name is not an accepted value.

       GL_INVALID_VALUE is generated by glGetStringi if index is outside the valid range for indexed state name.

NAME

       glGetMinmaxParameter - get minmax parameters

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 format of minmax table	|
       +----------------------------------+-------------------------------------+
       |GL_MINMAX_SINK			  | Value of the sink parameter 	|
       +----------------------------------+-------------------------------------+

NOTES

       glGetMinmaxParameter is present only if 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().
