# wslay\_event\_config\_set\_max\_recv\_msg\_length(3)

Set maximum length of a message that can be received

## NAME

wslay\_event\_config\_set\_max\_recv\_msg\_length - Set maximum length of a message that can be received

## SYNOPSIS

\#include \<wslay/wslay.h\>

- **void wslay\_event\_config\_set\_max\_recv\_msg\_length(wslay\_event\_context\_ptr *ctx*, uint64\_t *val*)**

  ## DESCRIPTION

*wslay\_event\_config\_set\_max\_recv\_msg\_length()* sets maximum length of a message that can be received. The length of message is checked by **wslay\_event\_recv()** function. If the length of a message is larger than this value, reading operation is disabled (same effect with **wslay\_event\_shutdown\_read()** call) and close control frame with **WSLAY\_CODE\_MESSAGE\_TOO\_BIG** is queued. If buffering for non-control frames is disabled, the library checks each frame payload length and does not check length of entire message.

The default value is **(1u \<\< 31)-1**.

## SEE ALSO
