-/* 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
-20040920 mvh Fixed the above option (failed in append mode)\r
-20040924 mvh Fixed warn in option\r
-20041117 mvh ELEKTA NKI-XVI0.1g RELEASE\r
-20050302 ljz Merant tracker ID #1867: Check on bad compression-ratio causing\r
- access violation.\r
-20050308 ljz+mvh ELEKTA NKI-XVI0.1j RELEASE\r
-20050411 mvh Fails on I178_s1_4H.3d mode 1: compression fails and written file corrupted\r
-20060903 mvh Added WRITE_MEM_XDR and QUERY_MEM_XDR\r
-20070330 mvh WRITE_XDR failed on G:\20605104_hypo lung\20605104_incl corr+doseab3.PACK\r
-20071015 mvh ELEKTA NKI-XVI3.08 RELEASE\r
-20080411 lsp+mw NULL->0 in WriteImage() ; __sun__ doesn't know <io.h>\r

-20090802 mvh ELEKTA NKI-XVI4.29 RELEASE\r
-20091209 lsp Added WRITE_MEM_RAW\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
- Use more space for pCompressed to be able to call WRITE_XDR with compression \r
- on small fields (<10 pixels for mode 2 or 4, <2 pixels for mode 1 and 3)\r
