Hi,
I have a problem which I don't really know what it is.
The POSE complained that the dynamic heap chunk with header address
0x0001CFF8 got corrupted. The size of the chunk (%chunk_size) was larger
than the currently accepted maximmum (%chunk_max)
I am currently using POSE 3.4
I have used the debugger but can't see where it is wrong. Here is snippet
code below Thank you in advance.
void dbGetStudentList(dbStudentList **ptrP)
{
dbStudentList *dbStudentListP;
STUDENT tempStudent;
UInt16 totalRecords;
UInt32 len, size, size1;
int index;
Char *StudentDBName = "NPET-Student";
totalRecords = CountRecord(StudentDBName);
//allocate memory to the pointer worth Nth record
size = sizeof(*dbStudentListP) +
totalRecords *
sizeof(dbStudentListP->names[0]);
dbStudentListP = MemPtrNew(size);
dbStudentListP->nStudents = totalRecords;
if(totalRecords)
{
size1 = sizeof(dbStudentListP->studentsRef[0]) * totalRecords;
//////////////////////
dbStudentListP->studentsRef = MemPtrNew( size1 );
for(index = 0; index < totalRecords; index++)
{
tempStudent = * ( ReadStudRecord(StudentDBName, index ) );
dbStudentListP->studentsRef[index].id =
tempStudent.studentRecordID;
len = StrLen(tempStudent.Name) + 1;
dbStudentListP->names[index] = MemPtrNew(len) ; //it complains
here
when there is more than 2 records
StrCopy(dbStudentListP->names[index], tempStudent.Name);
}
}
CloseDB();
setDBPtr();
*ptrP = dbStudentListP;
}
