fgluCheckExtension(3G) OpenGL Reference 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.
