Detailed Description

Constants and utility functions related to WebSocket opcodes.

WebSocket Opcodes are 4 bits. See RFC6455 section 5.2.

Function Documentation

bool websocketpp::frame::opcode::invalid ( value  v)
inline

Check if an opcode is invalid.

Invalid opcodes are negative or require greater than 4 bits to store.

Parameters
vThe opcode to test.
Returns
Whether or not the opcode is invalid.

Definition at line 130 of file frame.hpp.

bool websocketpp::frame::opcode::is_control ( value  v)
inline

Check if an opcode is for a control frame.

Parameters
vThe opcode to test.
Returns
Whether or not the opcode is a control opcode.

Definition at line 139 of file frame.hpp.

bool websocketpp::frame::opcode::reserved ( value  v)
inline

Check if an opcode is reserved.

Parameters
vThe opcode to test.
Returns
Whether or not the opcode is reserved.

Definition at line 118 of file frame.hpp.
