-/* Updates:\r
-When Who What\r
-19980212 ljz Creation (i.e. Removed from 'mbfield4.c')\r
-19980304 ljz Added QUIRT_NEXT_PARAMETER_FILE\r
-19980310 ljz Fix: XDRs were written in text-mode when\r
- quirt_init() is not called\r
-19980319 ljz Undone last change: _fmode is set in DllEntryPoint\r
-19980408 tp Moved M$-specific includes;\r
- removed AVS portability anyway\r
-19980611 mvh Added offset to write_raw (write into file)\r
-20000214 lsp Check file handle returned by open before use\r
-20000313 nd Two AVSerror messages added.\r
-20000322 lsp Matched compute func declaration with desc func\r
-20000630 ljz Added WRITE_RAW_LE, to write little-endian pixel-data\r
-20000806 lsp Compute func now 'int', conformal to ANSI C++\r
-20000821 ljz Added NkiCompression parameter to WRITE_XDR. If used,\r
- mode 2 is recommended.\r
-20000504 mvh Added write coordinates in header option to WRITE_XDR\r
-20010720 mvh Added option to write to stdout: pass "" as filename\r
-20010723 mvh Made it working by redefining write; setmode does not work\r
-20010725 bb Changed include order of windows.h and mbavs2q.h\r
- for MS6 compiler.\r
-20020124 mvh+kg The datatype in the header is now e.g. "xdr_integer"\r
- The datatypes as "integer" were intended as having native\r
- byte order, while we wrote bigendian (high byte first). Our\r
- older files read therefore OK on HP and SUN but not on linux.\r
-20020124 mvh+kg On AVS5 xdr_byte is illegal. Replace only that one by 'byte'\r
-20030311 bb Added check on write errors. Disc full errors during a\r
- write have nasty side-effects for other programs' open files.\r
- Added check on file handle to prevent closing of stdout.\r
-20030430 mvh Added append mode for WRITE_XDR\r
-20030717 ljz Added support for NkiCompressionModes 3 and 4 (4 is recommended)\r
-20040426 mvh ELEKTA NKI-XVI0.1 RELEASE\r
-20040910 mvh Write uncompressed and warn if the compress malloc fails, layout\r

-20050411 mvh Fails on I178_s1_4H.3d mode 1: compression fails and written file corrupted\r

-20091214 lsp 64 bits adaptations: pass high address of buffer as well,\r
- replaced int by AVSINT when requested, process buffer in chunks\r
- to be able to interpret return value of write() (signed int) correctly,\r
- replaced out-of-range constants 0xc0 and 0x80 by their signed equivalents\r
-20091216 lsp+ljz Prepared compression for more than 4294967295 (UINT_MAX) shorts\r
- by using bigger NKI_MODE2_64BITS struct (backwards compatible)\r
-20091216 lsp Disabled #define write for clarity: checked_write() is used throughout\r

+/* Updates:

+19980212 ljz Creation (i.e. Removed from 'mbfield4.c')
+19980304 ljz Added QUIRT_NEXT_PARAMETER_FILE
+19980310 ljz Fix: XDRs were written in text-mode when
+ quirt_init() is not called
+19980319 ljz Undone last change: _fmode is set in DllEntryPoint
+19980408 tp Moved M$-specific includes;
+ removed AVS portability anyway
+19980611 mvh Added offset to write_raw (write into file)
+20000214 lsp Check file handle returned by open before use
+20000313 nd Two AVSerror messages added.
+20000322 lsp Matched compute func declaration with desc func
+20000630 ljz Added WRITE_RAW_LE, to write little-endian pixel-data
+20000806 lsp Compute func now 'int', conformal to ANSI C++
+20000821 ljz Added NkiCompression parameter to WRITE_XDR. If used,
+ mode 2 is recommended.
+20000504 mvh Added write coordinates in header option to WRITE_XDR
+20010720 mvh Added option to write to stdout: pass "" as filename
+20010723 mvh Made it working by redefining write; setmode does not work
+20010725 bb Changed include order of windows.h and mbavs2q.h
+ for MS6 compiler.
+20020124 mvh+kg The datatype in the header is now e.g. "xdr_integer"
+ The datatypes as "integer" were intended as having native
+ byte order, while we wrote bigendian (high byte first). Our
+ older files read therefore OK on HP and SUN but not on linux.
+20020124 mvh+kg On AVS5 xdr_byte is illegal. Replace only that one by 'byte'
+20030311 bb Added check on write errors. Disc full errors during a
+ write have nasty side-effects for other programs' open files.
+ Added check on file handle to prevent closing of stdout.
+20030430 mvh Added append mode for WRITE_XDR
+20030717 ljz Added support for NkiCompressionModes 3 and 4 (4 is recommended)
+20040426 mvh ELEKTA NKI-XVI0.1 RELEASE
+20040910 mvh Write uncompressed and warn if the compress malloc fails, layout

+DESCRIPTION
+ WRITE_RAW: No header, no coordinates.
+ Data only are written (high byte first); optionally into an
+ existing file (if you specify an offset)
+
+ WRITE_RAW_LE: No header, no coordinates.
+ Data only are written (low byte first);
+ optionally into an existing file (if you specify an offset)
+
+ WRITE_XDR: Successively is written to file:
+ - The string '#AVS wants ...'.
+ - The optional Header info
+ - The contents of the optional Header file
+ - An ascii description of the Input field
+ - Optionally the coordinates (coord%axis%[%pixel%]=%coord%)
+ (%axis% is 1 based, %pixel% 0 based, %coord% is float)
+ - Two bytes containing ascii character 0x0c
+ - The Data in binary (high byte first).
+ Or, if NKI_Compression is greater than zero, compressed data.
+ - The Coordinates in binary IEEE float (high byte first)
