[strace PATCH 02/12] Add print_quoted_string flag to generate comment

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Because there are never enough print_quoted_string flags.

* defs.h (QUOTE_EMIT_COMMENT): New quoting flag macro constant.
* util.c (string_quote): Emit " /* " in the beginning and " */" in the
end if QUOTE_EMIT_COMMENT is passed.
(print_quoted_string): Increase alloc_size by 7 if QUOTE_EMIT_COMMENT is
passed.
