from the commands. Control returns to the application when the connection is established and Sterling Connect:Direct is ready for the first API request or when an error condition is set.

Following is the format for the ndmapi_connect() or ndmapi_connect_c() function:

int32 ndmapi_connect ERROR_H error, char * ndm_hostname, char * ndm_portname

The following table describes the parameters for the ndmapi_connect() or ndmapi_connect_c() function:

Parameter	Description	Value

error	A pointer to a Sterling Connect:Direct-defined structure	Pointer
	that contains error information or status information.

ndm_hostname	A pointer to the text specification of the Sterling	Null-
	Connect:Direct host to which the connection is made. If	terminated
	this parameter is not specified, the host name is	string
	determined by first checking the environment variable
	TCPHOST. If no value is specified, the tcp.host.name
	field in the CLI/API configuration file is checked. If no
	value is specified, the gethostbyname() command is
	invoked and the default value of ndmhost is used.

ndm_portname	A pointer to the host port number. If this parameter is	Pointer
	not specified, the environment variable TCPPORT is
	checked. If no value is specified, the value of the
	tcp.port in the CLI/API configuration file is checked. If
	no value is specified, the default value 1363 is used.

The ndmapi_connect() or ndmapi_connect_c() function has the following return codes:

Parameter	Description

NDM_NO_ERROR	A session was established with the server.

NDM_ERROR	A session was not established with the
	server. Consult the error structure for
	detailed error status.

The following sample function illustrates the use of ndmapi_connect() to connect to the sun1 host:

rc=ndmapi_connect (error, "sun1", "3122");

Terminating a Connection Using ndmapi_disconnect() or ndmapi_disconnect_c()

Use ndmapi_disconnect() or ndmapi_disconnect_c() to terminate a connection to Sterling Connect:Direct that was established by a call to ndmapi_connect() or ndmapi_connect_c(). The ndmapi_disconnect() or ndmapi_disconnect_c()function call is the following:

void ndmapi_disconnect

There are no parameters and no return codes for ndmapi_disconnect() or ndmapi_disconnect_c(). Following is a sample ndmapi_disconnect() function:

ndmapi_disconnect ();
