Hi, If a function is returning a pointer and if that pointer was returned by a malloc function , how do I free that pointer ? If I run valgrind , it will show memory leak since "k" was not freed. How do I free "k" in following ? Example: int * sum(int a, int b) { int sum; int *k=malloc(sizeof(int)); sum=a+b; k=∑ return k; } Thank you. -PLF
you use the free() function int * sum(int a, int b) { int sum; int *k=malloc(sizeof(int)); sum=a+b; k=∑ return k; free(k); }
Hi, Thanks for the response . Just wanted to know if one uses free() after a return statement will free() ever get called ? Thanks. -PLF
