Description
XDisplayString() returns the string that was passed to XOpenDisplay() when the current display was opened. On POSIX-conformant systems, if
the passed string was NULL, it returns the value of the DISPLAY environment variable when the current display was opened.
XDisplayString() is useful for printing error messages when XOpenDisplay() fails, and for applications that invoke the fork system call and
want to open a new connection to the same display from the child process.
The C language macro DisplayString() is equivalent and slightly more efficient. XDisplayName() is also a similar function.
