_lread info  Overview  Group

The _lread function reads data from the specified file. This function is provided for compatibility with 16-bit versions of Windows. Win32-based applications should use the ReadFile function.

UINT _lread(

Parameters

hFile

Identifies the specified file.

lpBuffer

Pointer to a buffer that contains the data read from the file.

uBytes

Specifies the number of bytes to be read from the file.

Return Values

The return value indicates the number of bytes actually read from the file. If the number of bytes read is less than uBytes, the function has reached the end of file (EOF) before reading the specified number of bytes.

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

If you are attempting to read from a floppy drive that does not have a floppy disk, the system displays a message box prompting the user to retry the operation. To prevent the system from displaying this message box, call the SetErrorMode function with SEM_NOOPENFILEERRORBOX.
