Synopsis

#include <nghttp3/nghttp3.h>

int nghttp3_conn_is_stream_writable(nghttp3_conn *conn, int64_t stream_id)

nghttp3_conn_is_stream_writable() returns nonzero if a stream identified by stream_id is writable. It is not writable if:

• the stream does not exist; or,

• the stream is closed (e.g., nghttp3_conn_close_stream() is called); or,

• the stream is QUIC flow control blocked (e.g., nghttp3_conn_block_stream() is called); or,

• the stream is input data blocked (e.g., NGHTTP3_ERR_WOULDBLOCK is returned from nghttp3_read_data_callback); or,

• the stream is half-closed local (e.g., nghttp3_conn_shutdown_stream_write() is called).
