neels gerrit-no-reply at lists.osmocom.orgHello Jenkins Builder, I'd like you to reexamine a change. Please visit https://gerrit.osmocom.org/c/libosmocore/+/15957 to look at the new patch set (#3). Change subject: utils.h: add OSMO_NAME_C_IMPL() macro ...................................................................... utils.h: add OSMO_NAME_C_IMPL() macro Provide a common implementation for foo_name_c() functions that base on foo_name_buf() functions. char *foo_name_c(void *ctx, example_t arg) { OSMO_NAME_C_IMPL(ctx, 64, "ERROR", foo_name_buf, arg) } Rationale: the most efficient way of composing strings that have optional parts or require loops for composition is by writing to a ready char[], and this in turn is easiest done by using OSMO_STRBUF_* API. Using such a basic name string implementation which typically returns a length, I often want a more convenient version that returns a char*, which can just be inlined in a "%s" string format -- crucially: skipping string composition when inlined in a LOGP(). This common implementation allows saving code dup, only the function signature is needed. Why not include the function signature in the macro? The two sets of varargs (1: signature args, 2: function call args) are hard to do. Also, having an explicit signature is good for readability and code grepping / ctags. Upcoming uses: in libosmocore in the mslookup (D-GSM) implementation (osmo_mslookup_result_name_c()), and in osmo_msc's codec negotiation implementation (sdp_audio_codecs_name_c(), sdp_msg_name_c(), ...).
