vfork creates read-only copy of the parent. You cannot call function or assign value to variable except pid_t. Use fork and it should succeed. PS: Please ask questions related to Algorithms, as it is algorithm group. You could get fast answers for this type of question on a relevant group. No offense, it is just a advice. It could save time for other people and YOU too. - Azhar.
