Created new SCOPE_ functions that don't depend on RAII_VAR. Besides generating less code, the use of the explicit SCOPE_EXIT macros capture the line number where the scope exited. The RAII_VAR versions can't do that. * SCOPE_ENTER(level, ...): Like SCOPE_TRACE but doesn't use RAII_VAR and therefore needs needs one of... * SCOPE_EXIT(...): Decrements the trace stack counter and optionally prints a message. * SCOPE_EXIT_EXPR(__expr, ...): Decrements the trace stack counter, optionally prints a message, then executes the expression. SCOPE_EXIT_EXPR(break, "My while got broken\n"); * SCOPE_EXIT_RTN(, ...): Decrements the trace stack counter, optionally prints a message, then returns without a value. SCOPE_EXIT_RTN("Bye\n"); * SCOPE_EXIT_RTN_VALUE(__return_value, ...): Decrements the trace stack counter, optionally prints a message, then returns the value specified. SCOPE_EXIT_RTN_VALUE(rc, "Returning with RC: %d\n", rc); Create an ast_str helper ast_str_tmp() that allocates a temporary ast_str that can be passed to a function that needs it, then frees it. This makes using the above macros easier. Example: SCOPE_ENTER(1, Format Caps 1: %s Format Caps 2: %s\n", ast_str_tmp(32, ast_format_cap_get_names(cap1, &STR_TMP), ast_str_tmp(32, ast_format_cap_get_names(cap2, &STR_TMP)); The calls to ast_str_tmp create an ast_str of the specified initial length which can be referenced as STR_TMP. It then calls the expression, which must return a char *, ast_strdupa's it, frees STR_TMP, then returns the ast_strdupa'd string. That string is freed when the function returns.
