4 /* NAME
5 /* argv_attr_print
6 /* SUMMARY
7 /* write ARGV to stream
8 /* SYNOPSIS
9 /* #include <argv_attr.h>
10 /*
11 /* int argv_attr_print(print_fn, stream, flags, ptr)
12 /* ATTR_PRINT_COMMON_FN print_fn;
13 /* VSTREAM *stream;
14 /* int flags;
15 /* void *ptr;
16 /* DESCRIPTION
17 /* argv_attr_print() writes an ARGV to the named stream using
18 /* the specified attribute print routine. argv_attr_print() is meant
19 /* to be passed as a call-back to attr_print(), thusly:
20 /*
21 /* ... SEND_ATTR_FUNC(argv_attr_print, (const void *) argv), ...
22 /* DIAGNOSTICS
23 /* Fatal: out of memory.
24 /*
25 /* The result value is zero in case of success, non-zero
26 /* otherwise.
