The first substitution removes the space before and after "Atom".
The second substitution changes 5 blanks at beginning of line to 3 blanks.

xinternatoms

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.
