port_addr_add()

Adds another static address to the local port.

Description

The port_addr_add() function is used to add an additional static address to the local port. This allows the port to listen on multiple IP addresses.

Syntax

  ;;; Adds another static address to the local port
  (@interface func (export "port_addr_add")
    ;;; Address to be added
    (param $addr (@witx const_pointer $addr_cidr))
    (result $error (expected (error $errno)))
  )

Parameters

• ctx: A mutable reference to the function environment.
• ip: A WebAssembly pointer to a __wasi_cidr_t structure that represents the IP address and prefix length of the address to be added.

Return Value

The function returns a Result indicating the outcome of the operation. If the operation is successful, Ok(Errno::Success) is returned. If an error occurs, an appropriate WasiError is returned.

Notes

• The port_addr_add() function adds another static address to the local port, allowing the port to listen on multiple IP addresses.
• The __wasi_cidr_t structure represents an IP address and prefix length. It contains two fields: ip for the IP address and prefix for the prefix length.
• The behavior and limitations of the port_addr_add() function may vary depending on the specific runtime environment and underlying networking implementation. It is important to consult the documentation or specifications of the specific environment to understand its behavior in that context.
