Call XdbeQueryExtension before of calling any Xdbe function | |
XdbeQueryExtension() tells to the caller if the Xdbe extension is present in | |
tthe X server, so it should be called for sanity. But like is said in | |
XdbeQueryExtension(3): | |
No other Xdbe functions may be called before this function. If a | |
client violates this rule, the effects of all subsequent Xdbe calls | |
that it makes are undefined. | |
it is mandatory call this function. | |
