+the returned value is ignored. +However, the error handler should not +call any functions (directly or indirectly) on the display +that will generate protocol requests or that will look for input events. +The previous error handler is returned. +.LP +The +.ZN XGetErrorText +function copies a null-terminated string describing the specified error code +into the specified buffer. +The returned text is in the encoding of the current locale. +It is recommended that you use this function to obtain an error description +because extensions to Xlib may define their own error codes +and error strings. +.LP +The +.ZN XDisplayName +function returns the name of the display that +.ZN XOpenDisplay +would attempt to use. +If a NULL string is specified, +.ZN XDisplayName +looks in the environment for the display and returns the display name that +.ZN XOpenDisplay +would attempt to use. +This makes it easier to report to the user precisely which display the +program attempted to open when the initial connection attempt failed. +.LP +The +.ZN XSetIOErrorHandler +sets the fatal I/O error handler. +Xlib calls the program's supplied error handler if any sort of system call +error occurs (for example, the connection to the server was lost). +This is assumed to be a fatal condition, +and the called routine should not return. +If the I/O error handler does return, +the client process exits. +.LP +Note that the previous error handler is returned. +.LP +The +.ZN XGetErrorDatabaseText +function returns a null-terminated message +(or the default message) from the error message +database. +Xlib uses this function internally to look up its error messages. +The text in the default_string argument is assumed +to be in the encoding of the current locale, +and the text stored in the buffer_return argument +is in the encoding of the current locale. +.LP +The name argument should generally be the name of your application. +The message argument should indicate which type of error message you want. +If the name and message are not in the Host Portable Character Encoding, +the result is implementation-dependent. +Xlib uses three predefined ``application names'' to report errors. +In these names, +uppercase and lowercase matter. +.IP XProtoError 1i +The protocol error number is used as a string for the message argument. +.IP XlibMessage 1i +These are the message strings that are used internally by the library. +.IP XRequest 1i +For a core protocol request, +the major request protocol number is used for the message argument. +For an extension request, +the extension name (as given by +.ZN InitExtension ) +followed by a period (\.) and the minor request protocol number +is used for the message argument. +If no string is found in the error database, +the default_string is returned to the buffer argument. +.SH "SEE ALSO" +XOpenDisplay(3X11), +XSynchronize(3X11) +.br +\fI\*(xL\fP |
