*
*NAME File APIs
*
*SYNOPSIS: These APIs are primitive File IO operations using ULONG as
* a file handle. They provide line-oriented access to text
* files. Equivalent functionality is available under both
* Windows and DOS/OS2, although error reporting is more limited
* under Windows.
*
*INTERFACE:
*
* APIERR FileOpenRead( PULONG pulFileHandle, const TCHAR * cpszFileName ) ;
* Opens a file for reading only. Returns FAPI error code.
* Windows returns only NO_ERROR or ERROR_FILE_NOT_FOUND.
*
* APIERR FileOpenWrite( PULONG pulFileHandle, const TCHAR * cpszFileName ) ;
* Creates a new file, deleting any existing file. Returns
* FAPI error code. Windows returns only NO_ERROR or
* ERROR_WRITE_FAULT.
*
* APIERR FileClose( ULONG ulFileHandle ) ;
* Closes a file opened by FileOpenRead or FileOpenWrite.
* Returns FAPI error code. Windows returns only NO_ERROR
* or ERROR_READ_FAULT (regardless of whether file was
* opened for reading or writing). Do not close if file
* was not successfully opened.
*
* APIERR FileReadLine( ULONG ulFileHandle, PSZ pszBuffer, UINT cbBuffer ) ;
* Reads a single line from the file, where a line is
* terminated by '\n'. Termination is left on the string.
* Returns ERROR_INSUFFICIENT_BUFFER to indicate EOF as well
* as a line longer than cbBuffer.
*
* APIERR FileWriteLine( ULONG ulFileHandle, const TCHAR * cpszBuffer ) ;
* Writes a null-terminated string to the file. Be sure
* that the string is "\r\n" terminated.
*
*
*
*CAVEATS: Windows cannot return as wide a variety of error codes as
* OS2, so Windows programs should take return codes
* other than NO_ERROR with a grain of salt.
*
* Treat the ULONG file handles as you would DosOpen file
* handles, e.g.
* - do not use before opening file
* - do not read file opened with FileOpenWrite, or vice versa
* - always close successfully opened files
*
