createbin(4)


createbin - createbin file format

Synopsis

#include <sys/str.h>

Description

The createbin command is used to create a structure template file to be used by kcrash.

Each template file begins with the createbin magic string.


	  #define  fvalid   'RC'	 /* file valid */

The template file starts with the following structure:


	  struct StrHdrType {
		ushort_t Id;		/* file	valid */
		ushort_t TableSz;	/* size	of table of names */
		ushort_t StrRelease;
		ushort_t StrVersion;
		ulong_t	FinalLfa;	/* end of file used by addbin */
		};

Following FinalLfa is a series of null terminated names and a long pointer into the file where this structure template starts.

	   10  |  \0|  \0|  \0|	 \0|  Offset to	template 11-14
	       | ___|____|____|____|
	   14  |  /0|  /0|  /0|	 \0|
	       | ___|____|____|____|

Each structure template starts with a headerType structure.


	  struct HeaderType {
		 uchar_t StringSz; /* length of	the longest string */
		 ushort_t TableSz; /* Size of the structure */
		};

After the header information is an entry for each structure element as follows:


	Element	name terminated	by a null.
	Element	type a byte that indicates the element type.
	An optional short for the size of arrays.
	Element	offset a short that contains the offset	from
	the beginning of the structure to this element.

	NOTE: Element type bit 7 if on indicates that the element type
 	      is an array.  Element type bit 6 indicates that the element
	      is a bit structure.  See sys/str.h for element type defines.
