Examples
The following example gets a pointer to each of two strings passed in as arguments, concatenates them in a new string, then releases the memory used by the original strings:
pbstring psppcls:: f_add_string(IPB_Session* session, pbstring arg1, pbstring arg2)
{
LPCTSTR pStr1,pStr2;
TCHAR tmp[100];
pbstring ret;
pStr1=session-> GetString(arg1);
pStr2=session-> GetString(arg2);
_tcscpy(tmp,pStr1);
_tcscat(tmp,pStr2);
ret = session -> NewString(tmp);
session-> ReleaseString(pStr1);
session-> ReleaseString(pStr2);
return ret ;
}
Usage
Do not use this function to release a string obtained using GetDateString, GetTimeString, GetDateTimeString, or GetDecimalString. Each of these Get methods has a corresponding Release method.
