Help¶

Size of an intermediate buffer used by sendmsg to repack data and therefore limit the number of sendto calls. The buffer is created in a static memory, so it does not impact stack/heap usage. In case the repacked message would not fit into the buffer, sendmsg sends each message part separately.

Direct dependencies¶

BSD_LIBRARY

(Includes any dependencies from ifs and menus.)

Default¶

128
