Determines if the extension exists.
Enhanced X-Windows Library (libXext.a)
XExtCodes *XinitExtension(DisplayPtr, Name) Display *DisplayPtr; char *Name;
The XinitExtension extension function determines if the extension exists. Then, it allocates storage for maintaining the information about the extension on the connection, chains this onto the extension list for the connection, and returns the information the stub implementor needs to access the extension.
The extension number in the XExtCodes data structure is needed in the other calls that follow. This extension number is unique only to a single connection.
| DisplayPtr | Specifies a pointer to the display. |
| Name | Specifies the name of the extension. |
| Null | Indicates the extension does not exist. |
