emsx

Create Bloomberg EMSX connection

Description

The emsx function creates an emsx object, which represents a Bloomberg^® EMSX connection. After you create an emsx object, you can use the object functions to create and route orders, and manage orders and routes. For details about Bloomberg EMSX, see the EMSX API Programmers Guide.

Creation

Syntax

c = emsx(servicename)

c = emsx(servicename,authid,serverip)

c = emsx(servicename,authid,serverip,portnumber)

c = emsx(servicename,authid,serverip,portnumber,terminalip)

Description

Local Connection

c = emsx(servicename) creates a connection to the local Bloomberg EMSX communications server using the service servicename.

Remote Connection

c = emsx(servicename,authid,serverip) creates a connection to a remote EMSX server using the specified service name, authentication identifier, and server IP address.

c = emsx(servicename,authid,serverip,portnumber) also specifies the port number for the remote connection.

c = emsx(servicename,authid,serverip,portnumber,terminalip) also specifies the IP address of the machine you use to access the Bloomberg Terminal for the remote connection.
