Examples

Create a Bloomberg connection, and then retrieve information for the last price field.

Create a Bloomberg B-PIPE connection using the IP address of the machine running the Bloomberg B-PIPE process. This example uses the Bloomberg B-PIPE C++ interface and assumes the following:

  • The authentication is Windows® authentication when you set authtype to 'OS_LOGON'.

  • The application name is blank because you are not connecting to Bloomberg B-PIPE using an application.

  • The IP address for the machine running the Bloomberg B-PIPE process is '111.11.11.112'.

  • The port number of the machine running the Bloomberg B-PIPE process is 8194.

c is a bloombergBPIPE object.

authtype = 'OS_LOGON';
appname = '';
ipaddress = {'111.11.11.112'};
port = 8194;

c = bloombergBPIPE(authtype,appname,ipaddress,port);

Return data as a table by setting the DataReturnFormat property of the bloombergBPIPE object. If you do not set this property, the fieldsearch function returns data as a cell array.

c.DataReturnFormat = 'table';

Return information for the search term LAST_PRICE.

f = 'LAST_PRICE';
d = fieldsearch(c,f);

Display the first three rows of the field information in d.
