Macros¶

NGHTTP2_VERSION¶: Version number of the nghttp2 library release

NGHTTP2_VERSION_NUM¶: Numerical representation of the version number of the nghttp2 library release. This is a 24 bit number with 8 bits for major number, 8 bits for minor and 8 bits for patch. Version 1.2.3 becomes 0x010203.

NGHTTP2_PROTO_VERSION_ID¶: The protocol version identification string of this library supports. This identifier is used if HTTP/2 is used over TLS.

NGHTTP2_PROTO_VERSION_ID_LEN¶: The length of NGHTTP2_PROTO_VERSION_ID.

NGHTTP2_PROTO_ALPN¶: The serialized form of ALPN protocol identifier this library supports. Notice that first byte is the length of following protocol identifier. This is the same wire format of TLS ALPN extension. This is useful to process incoming ALPN tokens in wire format.

NGHTTP2_PROTO_ALPN_LEN¶: The length of NGHTTP2_PROTO_ALPN.

NGHTTP2_CLEARTEXT_PROTO_VERSION_ID¶: The protocol version identification string of this library supports. This identifier is used if HTTP/2 is used over cleartext TCP.

NGHTTP2_CLEARTEXT_PROTO_VERSION_ID_LEN¶: The length of NGHTTP2_CLEARTEXT_PROTO_VERSION_ID.

NGHTTP2_VERSION_AGE¶: The age of nghttp2_info

NGHTTP2_DEFAULT_WEIGHT¶: The default weight of stream dependency.

NGHTTP2_MAX_WEIGHT¶: The maximum weight of stream dependency.

NGHTTP2_MIN_WEIGHT¶: The minimum weight of stream dependency.

NGHTTP2_MAX_WINDOW_SIZE¶: The maximum window size

NGHTTP2_INITIAL_WINDOW_SIZE¶: The initial window size for stream level flow control.

NGHTTP2_INITIAL_CONNECTION_WINDOW_SIZE¶: The initial window size for connection level flow control.

NGHTTP2_DEFAULT_HEADER_TABLE_SIZE¶: The default header table size.

NGHTTP2_CLIENT_MAGIC¶: The client magic string, which is the first 24 bytes byte string of client connection preface.

NGHTTP2_CLIENT_MAGIC_LEN¶: The length of NGHTTP2_CLIENT_MAGIC.

NGHTTP2_DEFAULT_MAX_SETTINGS¶: The default max number of settings per SETTINGS frame

NGHTTP2_INITIAL_MAX_CONCURRENT_STREAMS¶: Warning

Deprecated. The initial max concurrent streams is 0xffffffffu.

Default maximum number of incoming concurrent streams. Use nghttp2_submit_settings() with nghttp2_settings_id.NGHTTP2_SETTINGS_MAX_CONCURRENT_STREAMS to change the maximum number of incoming concurrent streams.

Note

The maximum number of outgoing concurrent streams is 100 by default.
