This function retrieves information about the first module associated with a process.
Syntax
BOOL WINAPI Module32First(
HANDLE hSnapshot,
LPMODULEENTRY32 lpme
);
Parameters
- hSnapshot
[in] Handle to the snapshot returned from a previous call to the CreateToolhelp32Snapshot function.
- lpme
[out] Pointer to a MODULEENTRY32 structure.
Return Value
TRUE indicates that the first entry of the module list has been copied to the buffer. FALSE indicates failure. The ERROR_NO_MORE_FILES error value, returned by GetLastError, indicates that no modules exist or the snapshot does not contain module information.
Remarks
The calling application must set the dwSize member of MODULEENTRY32 to the size, in bytes, of the structure.
Module32First changes dwSize to the number of bytes written to the structure. This number is never greater than the initial value of dwSize, but it can be smaller. If the value is smaller, do not rely on the values of members whose offsets are greater than this value. To retrieve information about other modules associated with the specified process, use the Module32Next function.
