GlobalGetAtomName function

Retrieves a copy of the character string associated with the specified global atom.

Syntax


UINT WINAPI GlobalGetAtomName(
  _In_   ATOM nAtom,
  _Out_  LPTSTR lpBuffer,
  _In_   int nSize
);

Parameters

nAtom [in]

Type: ATOM

The global atom associated with the character string to be retrieved.

lpBuffer [out]

Type: LPTSTR

The buffer for the character string.

nSize [in]

Type: int

The size, in characters, of the buffer.

Return value

Type: UINT

If the function succeeds, the return value is the length of the string copied to the buffer, in characters, not including the terminating null character.

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

Remarks

The string returned for an integer atom (an atom whose value is in the range 0x0001 to 0xBFFF) is a null-terminated string in which the first character is a pound sign (#) and the remaining characters represent the unsigned integer atom value.

Security Considerations

Using this function incorrectly might compromise the security of your program. Incorrect use of this function includes not correctly specifying the size of the lpBuffer parameter. Also, note that a global atom is accessible by anyone; thus, privacy and the integrity of its contents is not assured.
