| UINT _lread(hFile, lpBuffer, cbRead) | |||||

The _lread function reads data from the specified file.
hFile
Identifies the file to read from.
lpBuffer
Points to a buffer for the data read from the file.
cbRead
Specifies the number of bytes to read from the file.
The return value indicates the number of bytes actually read from the file. If the number of bytes read is less than cbRead, the function reached the end of the file (EOF) before reading the specified number of bytes. The return value is -1 if the function failed.
This function is maintained for compatibility with previous versions of Windows. Win32 applications should use the ReadFile function to read from a file.
