Call XdbeQueryExtension before of calling any Xdbe function
XdbeQueryExtension() tells to the caller if the Xdbe extension is present in the 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. --- st.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-)
