3.1.2 ACMSDI_FORM_RECORD Structure and Macro Call

Defined in the ACMSDI.H file, the ACMSDI_FORM_RECORD type declares form records and shadow records passed to and from presentation procedures. The code in Example 3–1 defines the ACMSDI_FORM_RECORD type and a macro ACMSDI_INIT_FORM_RECORD to initialize the form record structure.

Example 3–1 Form Record Definition and Initialization Macro

typedef struct {

 

int

data_length;

/** length of data record **/

void *data_record;

/** pointer to data record **/

int

shadow_length;

/** length of shadow record **/

void *shadow_record;

/** pointer to shadow record **/

} ACMSDI_FORM_RECORD;

 

#define ACMSDI_INIT_FORM_RECORD (record, data, shadow)\ {\

record.data_length = sizeof(data);\ record.data_record = &data;\ record.shadow_length = sizeof(shadow);\ record.shadow_record = &shadow;\

}\

3.1.3Prototypes and Code for Presentation Procedures and Version Routines

The ACMSDI.H file contains function prototypes for the presentation procedures and action routines that your code supplies. The file PPSTUBS.C contains stub modules you can use for linking your application (see Compaq TP Desktop Connector for ACMS Client Application Programming Guide).

3.2 Parameter Memory Allocation

The caller of a TP Desktop Connector service or presentation procedure is responsible for allocating the memory for the parameters of that routine. For calls to the TP Desktop Connector client services, the desktop client program must allocate the memory for all parameters passed in, for example, submitter_id and call_context. For the presentation procedures, the desktop client program can expect that TP Desktop Connector software allocates memory for all the parameters passed in and for all workspaces before it calls these procedures.
