95 * Name : BOOL ReadFileEx
96 * Purpose : The ReadFileEx function reads data from a file asynchronously.
97 * It is designed solely for asynchronous operation, unlike the
98 * ReadFile function, which is designed for both synchronous and
99 * asynchronous operation. ReadFileEx lets an application perform
100 * other processing during a file read operation.
101 * The ReadFileEx function reports its completion status asynchronously,
102 * calling a specified completion routine when reading is completed
103 * and the calling thread is in an alertable wait state.
104 * Parameters: HANDLE hFile handle of file to read
105 * LPVOID lpBuffer address of buffer
106 * DWORD nNumberOfBytesToRead number of bytes to read
107 * LPOVERLAPPED lpOverlapped address of offset
108 * LPOVERLAPPED_COMPLETION_ROUTINE lpCompletionRoutine address of completion routine
109 * Variables :
110 * Result : TRUE / FALSE
111 * Remark :
112 * Status : UNTESTED STUB
