GLGETSTRING(3G)			 OpenGL 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_numbermajor_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.
