In order to be able to swich on and off PtrGuard usage, SyncBuffer implements a typical usage pattern of PtrGuard, that is a data buffer referenced from inside a C allocated struct, in two ways: 1) using a PtrGuard to dierctly store a pointer to the Go buffer in C memory, or 2) allocating a C buffer of same size and syncing data back with C.memcpy(). The implementation can be chosen with the with_ptrguard build tag. Signed-off-by: Sven Anderson <sven@redhat.com> |
