The _OPENHOST function opens a Host which listens for new connections and returns a Host status handle.


Syntax

hostHandle = _OPENHOST("TCP/IP:8080")


Description

  • Creates an Illegal Function Call error if called with a string argument of the wrong syntax.
  • The port used in the syntax example is 8080.
  • Valid hostHandle values are negative numbers.
  • If the syntax is correct but they fail to begin/connect a hostHandle of 0 is returned.
  • Always check if the handle returned is 0 (failed) before continuing.
  • CLOSE hostHandle closes the host. A failed handle value of 0 does not need to be closed.
