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.
