    272 This function has the same semantic as the UNIX read() function. It transfers <count> bytes from the kernel File_Cache associated to the file identified by <fd_id>, to the user <buffer>, starting from the current file offset. The offset value is incremented by count.
     272This function has the same semantic as the UNIX read() function. It transfers up to <count> bytes from the kernel File_Cache associated to the file identified by <fd_id>, to the user <buffer>, starting from the current file offset. The number of bytes actually transferred can be smaller than the <count> argument if an EOF is encountered. The offset value is incremented by the number to bytes actually transferred.
