7 /* write DSN structure to stream
8 /* SYNOPSIS
9 /* #include <dsn_print.h>

11 /* int dsn_print(print_fn, stream, flags, ptr)

16 /* DESCRIPTION
17 /* dsn_print() writes a DSN structure to the named stream using
18 /* the specified attribute print routine. dsn_print() is meant
19 /* to be passed as a call-back to attr_print(), thusly:
20 /*
