XSynchronize(3) 						  XLIB FUNCTIONS						   XSynchronize(3)

NAME

       XSynchronize, XSetAfterFunction - enable or disable synchronization

SYNTAX

       int (*XSynchronize(Display *display, Bool onoff))();

       int (*XSetAfterFunction(Display *display, int (*procedure)()))();

ARGUMENTS

       display	 Specifies the connection to the X server.

       procedure Specifies the procedure to be called.

       onoff	 Specifies a Boolean value that indicates whether to enable or disable synchronization.

DESCRIPTION

       The XSynchronize function returns the previous after function.  If onoff is True, XSynchronize turns on synchronous behavior.  If onoff is
       False, XSynchronize turns off synchronous behavior.

       The specified procedure is called with only a display pointer.  XSetAfterFunction returns the previous after function.

XGetErrorDatabaseText() 												   XGetErrorDatabaseText()

Name
  XGetErrorDatabaseText - obtain error messages from the error database.

Synopsis
  XGetErrorDatabaseText(display, name, message,
	    default_string, buffer_return, length)
	Display display;
	char *name, *message;
	char *default_string;
	char *buffer_return;
	int length;

Arguments
  display      Specifies a connection to an X server; returned from XOpenDisplay().

  name	       Specifies the name of the application.

  message      Specifies the type of the error message. One of XProtoError, XlibMessage, or XRequest (see the "Description" section below).

  default_string
	       Specifies the default error message.

  buffer_return
	       Returns the error description. You allocate this memory.

  length       Specifies the size of the return buffer.

Description
  XGetErrorDatabaseText()  returns  a  message from the error message database.  Given name and message as keys, XGetErrorDatabaseText() uses
  the resource manager to look up a string and returns it in the buffer argument.  Xlib uses this function internally to look  up  its	error
  messages.  On a UNIX-based system, the error message database is usually /usr/lib/X11/XErrorDB.

  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, then the result is implementation-dependent.	Three  prede-
  fined message types are used by Xlib to report errors:

  XProtoError The protocol error number is used as a string for the message argument.

  XlibMessage These are the message strings that are used internally by Xlib.

  XRequest    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 InitExtension) followed by a period (.) and the minor request protocol number is used for the  mes-
	      sage argument.

  If no string is found in the error database, XGetErrorDatabaseText() returns the default_string that you specify to the buffer.  The string
  in buffer will be of length length.  The default_string is assumed to be in the encoding of the current locale.  The buffer_return text  is
  in the encoding of the current locale.
