mkchdr

MKCHDR(1)						      General Commands Manual							 MKCHDR(1)

NAME

       mkchdr - creates a C header file from a type table

SYNOPSIS

       mkchdr <tbl-file> [output-file]

DESCRIPTION

       mkchdr  will  generate  a  C header file from the given type table.  The C data structures will be written to the given output file.  If an
       output file is not given, the C header is written to stdout.

       The generated C data structure is the value representation that table driven encoder expects (and decoder returns) for the type definitions
       in  the	given type table.  The table driven encoder and decoder, etc.  routines do not use the generated header - they treat the data in a
       generic way.  The generated header file simply saves you the hassle of dealing with ASN.1 values in the same generic way.  Instead you  get
       properly named structs and field names.	You do not need to use mkchdr to use the table driven encoders etc. but it is recommended.

FILES

       snacc/tbl-tools/mkchdr/	   Source code for the mkchdr program

BUGS

       There is no means of customizing the generated data structure.
