XInternAtoms(3X) XLIB FUNCTIONS XInternAtoms(3X)NAME
XInternAtoms - returns atoms for specified names
SYNTAX
Status XInternAtoms(display, names, count, only_if_exists, atoms_return)
Display *display;
char **names;
int count;
Bool only_if_exists;
Atom *atoms_return;
ARGUMENTS
display Specifies the connection to the X server.
names Specifies the array of atom names.
count Specifies the number of .
only_if_exists
Specifies a Boolean value that indicates whether the atom must be created.
atoms_return
Returns the atoms.
DESCRIPTION
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; otherwise, it returns zero.
XInternAtoms can generate BadAlloc and BadValue errors.
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 argu-
ment, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this
error.

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 matter; the strings ``thing'', ``Thing'', and ``thinG'' all designate dif-
ferent atoms. The atom will remain defined even after the client's connection closes. It will become undefined only when the last connec-
tion 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; otherwise, 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 implementation-depen-
dent. 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; otherwise, 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 argu-
ment, the full range defined by the argument's type is accepted. Any argument defined as a set of alternatives can generate this
error.
