Why you might ask. Because it looks like the importFromWkt() increments the pointer as it’s parsing it so by the time it returns the pointer you passed in no longer points to the beginning of the array of char* pointers. Instead, it points to the end of the memory block. Shouldn’t you be assigning a temp pointer to the start of the array before you start parsing it? If you made it a const char** parameter this wouldn’t happen. <o:p></o:p></p><p class=MsoNormal style='text-autospace:none'><o:p> </o:p></p><p class=MsoNormal style='text-autospace:none'>Am I correct or did I use the functions incorrectly?<o:p></o:p></p><p class=MsoNormal style='text-autospace:none'><o:p> </o:p></p><p class=MsoNormal style='text-autospace:none'>Best regards,<o:p></o:p></p><p class=MsoNormal>Martin<o:p></o:p></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Times New Roman","serif"'><o:p> </o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
