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. PUBLISHED_FROM=faf454d4c52a2f07ea8ac084cf0bd11a0c9c9b3b

decl_name: "mg_broadcast"

|
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.
