FindAtomA function (winbase.h)

Searches the local atom table for the specified character string and retrieves the atom associated with that string.

Syntax

ATOM FindAtomA(
  [in] LPCSTR lpString
);

Parameters

[in] lpString

Type: LPCTSTR

The character string for which to search.

Alternatively, you can use an integer atom that has been converted using the MAKEINTATOM macro. See Remarks for more information.

Return value

Type: ATOM

If the function succeeds, the return value is the atom associated with the given string.

If the function fails, the return value is zero. To get extended error information, call GetLastError.

Remarks

Even though the system preserves the case of a string in an atom table, the search performed by the FindAtom function is not case sensitive.

If lpString was created by the MAKEINTATOM 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.

Note

The winbase.h header defines FindAtom as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
