_hread
The _hread
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.
long _hread(
|
HFILE hFile, |
// handle to file |
|
LPVOID lpBuffer, |
// pointer to
buffer for read data |
|
long lBytes |
// length, in
bytes, of data buffer |
|
); |
|
Parameters
hFile
Identifies
the specified file.
lpBuffer
Pointer to a
buffer that contains the data read from the file.
lBytes
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 lBytes, 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.
