nghttp2_submit_ping

Synopsis

#include <nghttp2/nghttp2.h>

int nghttp2_submit_ping(nghttp2_session *session, uint8_t flags, const uint8_t *opaque_data)

Submits PING frame. You don't have to send PING back when you received PING frame. The library automatically submits PING frame in this case.

The flags is currently ignored and should be NGHTTP2_FLAG_NONE.

If the opaque_data is non NULL, then it should point to the 8 bytes array of memory to specify opaque data to send with PING frame. If the opaque_data is NULL, zero-cleared 8 bytes will be sent as opaque data.

This function returns 0 if it succeeds, or one of the following negative error codes:

NGHTTP2_ERR_NOMEM
Out of memory.
