Function Documentation

constexpr unsigned int edm::soahelper::padding_needed ( size_t  iSizeSoFar,
unsigned int  iBoundary 
)

Given a leading memory size, iSizeSoFar, and an alignment boundary requirement of iBoundary, returns how much additional memory padding is needed. This function assumes that when iSizeSoFar==0 that we are already properly aligned.
