The _hread function reads data from the specified file. This function supports huge memory objects (that is, objects larger than 64K, allocated using the GlobalAlloc function).
hf
Identifies the file to be read.
hpvBuffer
Points to a buffer that is to receive the data read from the file.
cbBuffer
Specifies the number of bytes to be read from the file.
The return value indicates the number of bytes that the function read from the file, if the function is successful. If the number of bytes read is less than the number specified in cbBuffer, the function reached the end of the file (EOF) before reading the specified number of bytes. The return value is –1L if the function fails.
