|   The connectPresentationSpace function establishes a connection between your hllapi.js application program and the host presentation space.     Prerequisite Calls   There are not prerequisite calls for this function.     Call Parameters   
| Parameter name | Explanation |  
| psId | 1-character short name of the host presentation space. |  
| success | A callback function that takes one parameter (the _jsro object) and is called upon successful connection with the host Presentation Space. |  
| failure | A callback function that takes one 'data' parameter and is called upon a failed connection attempt |  
| disconnect | A callback function that takes one 'data' parameter and is called upon a disconnection event. |     Return Value   This function always returns 0.   Remarks   | 1. | This function is equivalent to HLLAPI Function Number 1. | 
| 2. | An hllpapi.js web application cannot be connected to multiple presentation spaces concurrently. Calls requiring the connectPresentationSpace function as a prerequisite use the currently connected presentation space. For example, if an application is connected to presentation space A, B, and C in that order, the application must connect to B or A again to issue functions. | 
| 4. | More than one hllapi.js application can share a presentation space, if the applications support sharing (that is, if they were developed to work together and if they exhibit predictable behavior). |
