Having Problem with allocation
January 04, 2003 01:24 PM
just for you have an idead i have this function and i have a message box to output a value to check to see if it was created but when i check the valeu within the function it works.. outside of it it doesn't .. it looks like it didn't do anything to the data .. "it's did use the &" ..
what am i doing wrong ?

this is the way i wrote fstreams a couple years ago hope this helps
//filework
#include *******************************
#include
class fbinappio
{
private:
int lastobjsaved;
int lastobjmade;
int i;
int obj[10];
fstream FILEHNDLE;
public:
fbinappio(){}
void openfile()
{
FILEHNDLE.open("object.dat",ios::app|ios::in|ios::out|ios::binary);
if(!FILEHNDLE)
{cout<<"COULND NOT OPEN FILE";exit(1);}
}
// fileload(int sizeofobject,&objptr);
// filesave(int lastobjmade,int lastobjsaved,int sizeofobj,void **objptr);
// }
//};
void filesave(int lastobjmade,int lastobjsaved,int sizeofobj,void **objptr)
{
openfile();
for(i=lastobjsaved;i<=lastobjmade;++i)
{
FILEHNDLE.write((char*)objptr,sizeofobj);
}
FILEHNDLE.close();
}
void fileload(int sizeofobject,void **objptr)
{ int i;
openfile();
FILEHNDLE.seekg(0, ios::end); // goto end
int endposition = FILEHNDLE.tellg(); // find where we are
int numofobjs = endposition / sizeofobject; // number of objects
for(i=0;i {
int position = i * sizeofobject; // number times size
FILEHNDLE.seekg(position); // bytes from begin
FILEHNDLE.read((char*)*objptr, sizeofobject);
}
FILEHNDLE.close();
}
};
