HLLAPI Programmers Guide or HP-UX SNAplus2 3270/3179G Users

 

Guide.

 

LUA API

 

The LUA API enables application programmers to write applications

 

that communicate with host applications at the request unit and

 

response unit (RU) level, and to send and receive data on both the

 

SSCP-LU session and the PLU-SLU session. This API can be used to

 

support LU 0, 1, 2, or 3 communication with the host.

 

An LUA application uses the node's LU type 0–3 resources to

 

communicate with a host application. You do not need to define any

 

additional resources.

 

For more information, refer to the HP-UX SNAplus2 LUA Programmers

 

Guide.

 

MS API

 

The Management Services (MS) API enables an application to

 

communicate with other MS products in an APPN network. An

 

application can be either NMVT-level or MDS-level, depending on the

 

type of MS data it sends and receives. SNAplus2 performs any data

 

conversion that is required.

 

For more information, refer to the HP-UX SNAplus2 MS Programmers

 

Guide.

 

NOF API

 

The NOF API can be used to write applications that administer

 

SNAplus2 configuration and management resources. For more

 

information, refer to the HP-UX SNAplus2 NOF Programmers Guide.

 

Windows APIs

For Windows

The SNAplus2 client software includes API libraries that are fully

 

compatible with Microsoft SNA Server and the Windows Open Systems

 

Architecture (WOSA), enabling applications written for SNA Server to

 

run unchanged on the SNAplus2 Windows client.

 

SNAplus2 supports the following WOSA APIs:
