mtcp_getconf - retrieve the running configuration of mOS application #include <mtcp_api.h> "int mtcp_getconf(struct mtcp_conf *" "conf" ); mtcp_getconf () call is used to fetch the current running configuration of the mOS core. The "conf" argument is a pointer to a user-allocated "struct mtcp_conf" that contains a number of fields including:

20 "num_cores" An integer that shows the total number of cores the mOS core is using.

20 "max_concurrency" An integer that holds how many ongoing flows each core thread manages concurrently. Default value is 100000.

20 "max_num_buffers" An integer that holds the maximum number of socket buffers each core thread can hold. Default value is 100000.

20 "rcvbuf_size" An integer that holds the size of the TCP receive buffer. Default value is 8KB.

20 "tcp_timeout" An integer that holds the idle flow expiry timeout of the monitoring flow. Default value is 30 secs. """""""""""""""""""""""""""""""""""""""""""""""""""""""""""
