<function>glXQueryExtensionsString</function> returns a pointer to a string describing
|
||
|
|
which GLX extensions are supported on the connection. The string
|

|
|
is null-terminated and contains a space-separated list of
|
||
|
|
extension names. (The extension names themselves never contain
|
||
|
|
spaces.) If there are no extensions to GLX, then the empty string is
|
||
|
|
returned.
