SaMakeCbsByGroup
Make an SaCallbackStruct from one group of an SaCallbackStruct callback structure.
#include "SaPopCalls.h"
SaCallbackStruct* SaMakeCbsByGroup(SaCallbackStruct *cbs,
int group);
Arguments
- cbs
- SaCallbackStruct callback structure.
- group
- Specifies which group is to be used to make the return
SaCallbackStruct callback structure. A group is defined by the results of a single SQL SELECT statements execution. Sybase Data Objects allow multiple SELECT statements in a single Data Object, resulting in multiple groups of data.
Return Values
An SaCallbackStruct containing the data from one group of an SaCallbackStruct. A NULL pointer is returned if cbs is NULL or if the group specification is invalid.
SaMakeCbsByGroup returns a malloc'd SaCallbackStruct given a callback structure. The group parameter specifies which group in cbs is used to make the return SaCallbackStruct. If cbs is NULL or an invalid group specification is used, a NULL pointer is returned. Use SaFreeCbs() to deallocate this memory when it is no longer needed. The returned structure should be considered read-only data. Also, the actual data values in the structure should only be used while the underlying data is valid. This is usually after the Population callback function returns, although it may extend beyond that if the data is cached and not overwritten.
#include "SaConsoleCalls.h"
void SaPopulateFields(list, client_data, cbs)
Widget list;
XtPointer client_data;
SaCallbackStruct *cbs;
{
SaCallbackStruct *pcbs;
pcbs = SaMakeCbsStartStopCol(cbs, 0, 5);
SaPopulateTextFieldByCol(UxGetWidget(textField3),0,pcbs);
SaPopulateTextFieldByCol(UxGetWidget(textField4),1,pcbs);
SaPopulateTextFieldByCol(UxGetWidget(textField6),2,pcbs);
SaPopulateTextFieldByCol(UxGetWidget(textField5),3,pcbs);
SaPopulateTextFieldByCol(UxGetWidget(textField8),4,pcbs);
SaPopulateTextFieldByCol(UxGetWidget(textField7),5,pcbs);
SaFreeCbs(pcbs);
pcbs = SaMakeCbsByCol(cbs, 2);
SaPopulateTitleAndIcon(UxGetWidget(topLevelShell1),
NULL,pcbs);
SaFreeCbs(pcbs);
pcbs = SaMakeCbsByGroup(cbs, 0);
SaPopulateList(UxGetWidget(scrolledList1), NULL, pcbs);
SaFreeCbs(pcbs);
pcbs = SaMakeCbsStartColRange(cbs, 6, 1);
SaPopulateTextField(UxGetWidget(textField7), NULL,pcbs);
SaFreeCbs(pcbs);
}
