# The SMBIOS interfaces defined in <sys/smbios.h> include a set of integer-to-
# string conversion routines for the various constants defined in the SMBIOS
# spec.  These functions are used by smbios(1M) and prtdiag(1M) and can be
# leveraged by other clients as well.  To simplify maintenance of the source
# base, this shell script automatically generates the source code for all of
# these functions from the <sys/smbios.h> header file and its comments.  Each
# set of constants should be given a unique #define prefix, listed in the
# tables below.  The smbios_*_name() functions return the identifier of the
# cpp define, and the smbios_*_desc() functions return the text of the comment.
