sock_set_opt_size

sock_set_opt_size()

Sets the size of a particular option for the socket.

Description

The sock_set_opt_size() function sets the size of a specific socket option for the given socket descriptor.

Syntax

  ;;; Note: This is similar to `setsockopt` in POSIX for SO_RCVBUF
  ;;; Set size of particular option for this socket
  (@interface func (export "sock_set_opt_size")
    ;;; Socket descriptor
    (param $fd $fd)
    ;;; Socket option to be set
    (param $sockopt $sock_option)
    ;;; Buffer size
    (param $size $filesize)
    (result $error (expected (error $errno)))
  )

Parameters

  • ctx: A mutable reference to the function environment.
  • sock: The socket descriptor.
  • opt: The socket option to be set.
  • size: The size value to set for the option.

Return Value

The function returns an Errno value indicating the outcome of the operation. If the operation is successful, Errno::Success is returned. If an error occurs, an appropriate Errno value is returned.

Notes

  • The sock_set_opt_size() function sets the size of a specific socket option for the specified socket descriptor.
  • The specific socket option to set is determined by the opt parameter.
  • The size value to set for the option is specified by the size parameter.
  • The behavior and limitations of the sock_set_opt_size() 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.
