* $Log: asnwrite.cpp,v $
* Revision 1000.1  2004/06/01 19:14:43  gouriano
* PRODUCTION: UPGRADED [GCC34_MSVC7] Dev-tree R1.10
*
* Revision 1.10  2004/05/17 20:59:07  gorelenk
* Added include of PCH ncbi_pch.hpp
*
* Revision 1.9  2001/02/13 20:44:24  vakatov
* Use `reinterpret_cast<IoFuncType>(WriteAsn)' instead of a more safe
* (but not-compilable by MIPSpro7.3 compiler on IRIX) `extern "C"'
* pre-declaration.
*
* Revision 1.8  2001/02/10 05:00:17  lavr
* ctools added in #includes
*
* Revision 1.7  2000/11/29 17:25:16  vasilche
* Added possibility to change ASNIO mode (mainly for XML output).
* Fixed warnings on 64 bit compilers.
*
* Revision 1.6  1999/11/24 20:18:19  golikov
* flush moved from CreateSubNodes to PrintChildren -> loose of text fixed
*
* Revision 1.5  1999/05/15 23:00:59  vakatov
* Moved "asnio" and "asnwrite" modules to the (new) library
* "xasn"(project "asn")
*
* Revision 1.4  1999/04/15 21:59:58  vakatov
* [MSVC++]  Added "LIBCALLBACK" to the WriteAsn() proto
*
* Revision 1.3  1999/04/14 17:26:52  vasilche
* Fixed warning about mixing pointers to "C" and "C++" functions.
*
* Revision 1.2  1999/02/17 22:03:16  vasilche
* Assed AsnMemoryRead & AsnMemoryWrite.
* Pager now may return NULL for some components if it contains only one
* page.
*
* Revision 1.1  1999/01/28 15:11:09  vasilche
* Added new class CAsnWriteNode for displaying ASN.1 structure in HTML page.
