Function Macro

GLibassert_cmpmem

Declaration [src]

#define g_assert_cmpmem (
  m1,
  l1,
  m2,
  l2
)

Description [src]

Debugging macro to compare memory regions. If the comparison fails, an error message is logged and the application is either terminated or the testcase marked as failed.

The effect of g_assert_cmpmem (m1, l1, m2, l2) is the same as g_assert_true (l1 == l2 && memcmp (m1, m2, l1) == 0). The advantage of this macro is that it can produce a message that includes the actual values of l1 and l2.

m1 may be NULL if (and only if) l1 is zero; similarly for m2 and l2.

  g_assert_cmpmem (buf->data, buf->len, expected, sizeof (expected));
