XInternAtom(3)				  XLIB FUNCTIONS			   XInternAtom(3)

NAME
       XInternAtom, XInternAtoms, XGetAtomName, XGetAtomNames - create or return atom names

SYNTAX
       Atom XInternAtom(Display *display, char *atom_name, Bool only_if_exists);

       Status XInternAtoms(Display *display, char **names, int count, Bool only_if_exists, Atom
	      *atoms_return);

       char *XGetAtomName(Display *display, Atom atom);

       Status XGetAtomNames(Display *display, Atom *atoms, int count, char **names_return);

ARGUMENTS
       atom	 Specifies the atom for the property name you want returned.

       atoms	 Specifies the array of atoms.

       atom_name Specifies the name associated with the atom you want returned.

       atoms_return
		 Returns the atoms.

       count	 Specifies the number of atom names in the array.

       count	 Specifies the number of atoms in the array.

       display	 Specifies the connection to the X server.

       names	 Specifies the array of atom names.

       names_return
		 Returns the atom names.

       only_if_exists
		 Specifies a Boolean value that indicates whether the atom must be created.

DESCRIPTION
       The XInternAtom function returns the atom identifier associated with the specified
       atom_name string.  If only_if_exists is False, the atom is created if it does not exist.
       Therefore, XInternAtom can return None.	If the atom name is not in the Host Portable
       Character Encoding, the result is implementation-dependent.  Uppercase and lowercase mat-
       ter; the strings ``thing'', ``Thing'', and ``thinG'' all designate different atoms.  The
       atom will remain defined even after the client's connection closes.  It will become unde-
       fined only when the last connection to the X server closes.

       XInternAtom can generate BadAlloc and BadValue errors.

       The XInternAtoms function returns the atom identifiers associated with the specified
       names.  The atoms are stored in the atoms_return array supplied by the caller.  Calling
       this function is equivalent to calling XInternAtom for each of the names in turn with the
       specified value of only_if_exists, but this function minimizes the number of round-trip
       protocol exchanges between the client and the X server.

       This function returns a nonzero status if atoms are returned for all of the names; other-
       wise, it returns zero.

       XInternAtoms can generate BadAlloc and BadValue errors.

       The XGetAtomName function returns the name associated with the specified atom.  If the
       data returned by the server is in the Latin Portable Character Encoding, then the returned
       string is in the Host Portable Character Encoding.  Otherwise, the result is implementa-
       tion-dependent.	To free the resulting string, call XFree.

       XGetAtomName can generate a BadAtom error.

       The XGetAtomNames function returns the names associated with the specified atoms.  The
       names are stored in the names_return array supplied by the caller.  Calling this function
       is equivalent to calling XGetAtomName for each of the atoms in turn, but this function
       minimizes the number of round-trip protocol exchanges between the client and the X server.

       This function returns a nonzero status if names are returned for all of the atoms; other-
       wise, it returns zero.

       XGetAtomNames can generate a BadAtom error.

DIAGNOSTICS
       BadAlloc  The server failed to allocate the requested resource or server memory.

       BadAtom	 A value for an Atom argument does not name a defined Atom.

       BadValue  Some numeric value falls outside the range of values accepted by the request.
		 Unless a specific range is specified for an argument, the full range defined by
		 the argument's type is accepted.  Any argument defined as a set of alternatives
		 can generate this error.
