why qstringlist *ps "Segmentation fault"?

[lanmanck]

i want to init QStringList through a function,
my code:

QStringList qs;
initqstringlist(&qs);
 
the func is:
int void initqstringlist(QStringList *qs)
{
   qs->append("1");  //Segmentation fault
   qs->append("2");
}

QStringList qs;
initqstringlist(&qs);

the func is:
int void initqstringlist(QStringList *qs)
{
   qs->append("1");  //Segmentation fault
   qs->append("2");
}

To copy to clipboard, switch view to plain text mode 

why it report "Segmentation fault"? do i misunderstand the class?

probably QStringList qs; is out of scope and since qs is created on stack, it automatically is deleted.

you mast transmit to your initqstringlist valid pointer

QStringList* lst = new QStringList;
void initqstringlist(lst);

QStringList* lst = new QStringList;
void initqstringlist(lst);

To copy to clipboard, switch view to plain text mode 

and what is this declaration meant:
int void initqstringlist()
???

Attach minimal compilable example please.

sorry,i make a mistake,it is:
inline void initqstringlist(QStringList *qs);

but ,the variable “qs” is a member,declared in xxx.h:
public:
QStingList qs;
does it have be a pointer?

[spirit]

no, it should work fine.
can you show as compilable example?

i figured it out .
i use memset() before.
thank everyone.
