Atoms
In Microsoft ® Windows ® , an atom table is a system-defined table that stores strings and corresponding identifiers. An application places a string in an atom table and receives a 16-bit integer, called an atom , that can be used to access the string. A string that has been placed in an atom table is called an atom name .
