Introduction to Writing Custom Programs

The Sterling Connect:Direct Application Programming Interface (API) allows you to write custom programs in either C or C++ to use with Sterling Connect:Direct. With the C functions or the C++ classes, you can create programs to perform the following tasks:

vEstablish a connection to the Sterling Connect:Direct server

vDisconnect from the server

vReceive command responses from the server

vSend commands to the server

This topic describes the format of the Sterling Connect:Direct API functions and classes and provides samples of their use. Sample programs are provided that use the Sterling Connect:Direct API functions and classes to issue commands and receive responses from the Sterling Connect:Direct server.

Compiling Custom Programs

	After you write a custom program, you must compile it, using a C or C++
	compiler. Refer to the following information to determine what minimum C++
	compiler version to use for each platform:

Platform		C++ Compiler

AIX		IBM XL C++ V8.0 for AIX

Sun Solaris		SPARC/x86 C++5.7

HP		aCC: HP ANSI C++ B3910B A.03.73

HP-Itanium		aCC: HP ANSI C++ B3910B A.06.07

Linux		c++ version 3.3.3

	Use the commands defined in the following table to compile a custom C++
	program using the C++ API calls:

Platform	C++ Compile Command

AIX

64-bit	/usr/vacpp/bin/xlC -q64 -qinline -I../include -+ -o sdksample sdksample.C ../lib/ndmapi64.a -lbsd -ldl
	-lsrc -lpthreads

32-bit	/usr/vacpp/bin/xlC -qinline -I../include -+ -o sdksample sdksample.C ../lib/ndmapi.a -lbsd -ldl -lsrc
	-lpthreads

Sun

32-bit

Note: If /usr/ucblib is not in the LD_LIBRARY_PATH variable, add -R/usr/ucblib to the compile command.
