int __note (int handle);
Required Header |
<io.h> |
Return Value
This function returns the TTRz if the operation was successful. -1 indicates an error.
Parameters
handle
The low level I/O handle to the open file
Remarks
The __note function returns the TTRz of the last read or written block, and may be used to create directory entry data for Load-Library members. Care must be taken when executing this function to make sure that the buffer routines have commited a written block. This happens when a type U file has been supplied all the data specified by the two-byte short integer length included in the data stream.
Use _fileno to get the low-level handle of a stream.
Not all file types allow taking NOTE.
