cmemory-leaksmallocfreesetjmp

Should free() been called after longjmp()?

In this simple code should I take care about memory freeing in default case to escape from memory leak or can I use allocated memory? Does longjmp also revert memory allocations?

#include <setjmp.h>
#include <stdlib.h>
#include <stdio.h>

int main(int argc, const char* argv)
{
jmp_buf jmpbuf;

int *p=NULL;

switch(setjmp(jmpbuf)){
case 0:
    p=(int *) malloc(10*sizeof(int));
    printf("%p\n",p);
    longjmp(jmpbuf,1);
    break;
default:
    printf("%p\n",p);
    free(p);
}


return 0;
}
Solution

  • No, longjmp does not revert dynamic memory allocations.
