Sandbox Functions Reference

The following functions, which are all provided by ebuild.sh, handle working with the sandbox.

Function Details
addread Add one single additional item to the sandbox allowed read list.
addwrite Add one single additional item to the sandbox allowed write list. Note: If at all possible, use addpredict instead. Using addwrite is not an appropriate alternative to making your package build sandbox-friendly.
adddeny Add one single additional item to the sandbox deny (read/write) list.
addpredict Add one single additional item to the sandbox predict (pretend to allow write) list.

None of these functions accept multiple arguments in one call. The sandbox is recursive, so to allow predicted writes to /foo/bar and /foo/baz, addpredict /foo would be sufficient.

See Sandbox for details on how the sandbox works. See Handling Access Violations for how to handle sandbox-related build problems.
