C++ (Cpp) EnforceLimits Examples

Example #1

File: txt_spinctrl.c Project: Slipyx/Mint-Doom

static void FinishEditing(txt_spincontrol_t *spincontrol)
{
    switch (spincontrol->type)
    {
        case TXT_SPINCONTROL_INT:
            spincontrol->value->i = atoi(spincontrol->buffer);
            break;

        case TXT_SPINCONTROL_FLOAT:
            spincontrol->value->f = (float) atof(spincontrol->buffer);
            break;
    }

    spincontrol->editing = 0;
    EnforceLimits(spincontrol);
}
