fgluCheckExtension(3G)

NAME
     fgluCheckExtension - determines if an extension name is supported


FORTRAN SPECIFICATION
     LOGICAL*1 fgluCheckExtension( CHARACTER*256 extName,
                                   CHARACTER*256 extString )


PARAMETERS
     extName    Specifies an extension name.

     extString  Specifies a space-separated list of extension names supported.

DESCRIPTION
     fgluCheckExtension returns GL_TRUE if extName is supported otherwise
     GL_FALSE is returned.

     This is used to check for the presence for OpenGL, GLU or GLX extension
     names by passing the extension strings returned by glGetString,
     fgluGetString, glXGetClientString, glXQueryExtensionsString, or
     glXQueryServerString, respectively, as extString.

NOTES
     Cases where one extension name is a substring of another are correctly
     handled.

     There may or may not be leading or trailing blanks in extString.

     Extension names should not contain embedded spaces.

     All strings are null-terminated.
