This call returns the fully qualified drive, path, file name, and extension associated with a referenced module handle.
Syntax
DosGetModName (ModuleHandle, BufferLength, Buffer)
Parameters
- ModuleHandle (HMODULE) - input
- Handle of the dynamic link module being referenced.
- BufferLength (USHORT) - input
- Maximum length of the buffer, in bytes, where the name is stored.
- Buffer (PCHAR) - output
- Address of the buffer where the fully qualified drive, path, filename, and extension of the dynamic link module are stored.
Return Code
- rc (USHORT) - return
- Return code descriptions are:
- 0 NO_ERROR
- 6 ERROR_INVALID_HANDLE
- 24 ERROR_BAD_LENGTH
- 95 ERROR_INTERRUPT
Remarks
The handle returned by either a DosGetModHandle or a DosLoadModule request can be used with this call. An error is returned if the buffer is not large enough for the module name.
