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.
