mongoose/docs/c-api/net.h/mg_broadcast.md
Dmitry Frank 23122b327c Remove old docs, rename docs_new to docs 
It would be probably good idea to also remove tools/docgen.py and
asciidoc.mk, but asciidoc.mk is still mentioned under `cloud/doc`, which
may contain some useful info which we'll need at least to review before
removing.

mg_broadcast() mg_broadcast func void mg_broadcast(struct mg_mgr *, mg_event_handler_t func, void *, size_t);

Pass a message of a given length to all connections.

Must be called from a thread that does NOT call mg_mgr_poll(). Note that mg_broadcast() is the only function that can be, and must be, called from a different (non-IO) thread.

func callback function will be called by the IO thread for each connection. When called, event would be MG_EV_POLL, and message will be passed as ev_data pointer. Maximum message size is capped by MG_CTL_MSG_MESSAGE_SIZE which is set to 8192 bytes.
