Writing Custom C Programs

If you write a custom program using the C API calls, you must include the header

file ndmapi.h and link it with ndmapi.a. A sample program called apicheck.c is

provided.

For Java programming, you can call the C API functions by using the JNI and the

libndmapi shared objects: libndmapi.sl for HP and libndmapi.so for the other

supported platforms. Although the JNI is supported, the Sterling Connect:Direct

Java Application Interface is recommended for Java programs that invoke the

services of Sterling Connect:Direct.

Note: The environment variable NDMAPICFG must be set to the pathname of the

client configuration file. Refer to “Overview of the Command Line Interface” on

page 1 for instructions on setting the environment variable.

Use the following Sterling Connect:Direct API functions for C and C++ programs:

C++ Function C Function Description

ndmapi_connect() ndmapi_connect_c() Establishes a connection with the server.

Specify the node to connect to in the

ndm_nodespec pointer or in the CLI/API

Configuration Information file. If the call is

successful, NDM_NO_ERROR is returned.

Control returns to the application when the

connection is established and is ready for the

first API request.
