NAME

       gluErrorString - produce an error string from a GL or GLU error code

C SPECIFICATION

       const GLubyte * gluErrorString( GLenum error )

PARAMETERS

       error  Specifies a GL or GLU error code.

DESCRIPTION

       gluErrorString  produces  an  error  string  from  a  GL  or  GLU  error code. The string is in ISO Latin 1 . For example, gluErrorString(-
       GL_OUT_OF_MEMORY) returns the string out of memory.

       The standard GLU error codes are GLU_INVALID_ENUM, GLU_INVALID_VALUE, and GLU_OUT_OF_MEMORY.  Certain other GLU functions can  return  spe-
       cialized error codes through callbacks.	See the glGetError reference page for the list of GL error codes.

ERRORS

       NULL is returned if error is not a valid GL or GLU error code.

NAME

       gluGetString - return a string describing the GLU version or GLU extensions

C SPECIFICATION

       const GLubyte * gluGetString(GLenum name);

PARAMETERS

       name
	   Specifies a symbolic constant, one of GLU_VERSION, or GLU_EXTENSIONS.

DESCRIPTION

       gluGetString returns a pointer to a static string describing the GLU version or the GLU extensions that are supported.

       The version number is one of the following forms:

       major_number.minor_numbermajor_number.minor_number.release_number.

       The version string is of the following form:

       version number<space>vendor-specific information

       Vendor-specific information is optional. Its format and contents depend on the implementation.

       The standard GLU contains a basic set of features and capabilities. If a company or group of companies wish to support other features,
       these may be included as extensions to the GLU. If name is GLU_EXTENSIONS, then gluGetString returns a space-separated list of names of
       supported GLU extensions. (Extension names never contain spaces.)

       All strings are null-terminated.

NOTES

       gluGetString only returns information about GLU extensions. Call glGetString to get a list of GL extensions.

       gluGetString is an initialization routine. Calling it after a glNewList() results in undefined behavior.

ERRORS

       NULL is returned if name is not GLU_VERSION or GLU_EXTENSIONS.
