[Linphone-developers] use proper printf rather than ugly cast in coreapi/linphonecore.c

[Mike Frysinger]

it looks like in order to get rid of a warning, someone did:
snprintf(clen,sizeof(clen),"%u",(unsigned int)strlen(dtmf_body));
that's just silly ... strlen returns a size_t, not an unsigned int.
so just use a proper printf format string and everything is fine:
snprintf(clen,sizeof(clen),"%zi",strlen(dtmf_body));
