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.
