AddAtom
The AddAtom function adds a character string to the local atom table and returns a unique value (an atom) identify-
ing the string.
AddAtom: procedure
(
lpString: string
);
stdcall;
returns( "eax" );
external( "__imp__******@4" );
Parameters
lpString
[in] Pointer to the null-terminated string to be added. The string can have a maximum size of 255 bytes. Strings
differing only in case are considered identical. The case of the first string added is preserved and returned by the
GetAtomName function.
Alternatively, you can use an integer atom that has been converted using the MAKEINTATOM macro. See the
Remarks for more information.
Return Values
If the function eeds, the return value in EAX is the newly created atom.
If the function fails, the return value is zero. To get extended error information, call GetLastError.
Remarks
The AddAtom function stores no more than one copy of a given string in the atom table. If the string is already in the
table, the function returns the existing atom and, in the case of a string atom, increments the string's reference count.
If lpString has the form "#1234", AddAtom returns an integer atom whose value is the 16-bit representation of the
decimal number specified in the string (0x04D2, in this example). If the decimal value specified is 0x0000 or is
greater than or equal to 0xC000, the return value is zero, indicating an error. If lpString was created by the MAKEIN-
TATOM macro, the low-order word must be in the range 0x0001 through 0xBFFF. If the low-order word is not in
this range, the function fails.
If lpString has any other form, AddAtom returns a string atom.
