all — check whether all elements of a boolean vector are true
bool all( | bvec x); |
x Specifies the vector to be tested for truth.
all returns true if all elements of x are true and false otherwise. It is functionally equivalent to:
bool all(bvec x) // bvec can be bvec2, bvec3 or bvec4
{
bool result = true;
int i;
for (i = 0; i < x.length(); ++i)
{
result &= x[i];
}
return result;
}
