C/C++ zero 系列

bzero

  • #include <strings.h>
  • void bzero(void *s, size_t n);
  • The bzero() function erases the data in the n bytes of the memory
  • starting at the location pointed to by s, by writing zeros (bytes containing ‘\0’) to that area.
  • return
    • None.

      explicit_bzero

      • #include <strings.h>
  • void explicit_bzero(void *s, size_t n);
  • The explicit_bzero() function performs the same task as bzero().
  • It differs from bzero() in that it guarantees that compiler optimizations will not remove the erase operation if the compiler deduces that the operation is “unnecessary”.
  • return
    • None.
