[−][src]Function casperlabs_contract::ext_ffi::ret
pub unsafe extern "C" fn ret(value_ptr: *const u8, value_size: usize) -> !
This function causes a Trap, terminating the currently running module,
but first copies the bytes from value_ptr to value_ptr + value_size to
a buffer which is returned to the calling module (if this module was
invoked by call_contract or call_versioned_contract). Additionally, the known
casperlabs_types::uref::URefs of the calling context are augmented with the
casperlabs_types::uref::URefs de-serialized from wasm memory offset
extra_urefs_ptr to extra_urefs_ptr + extra_urefs_size. This function will cause a
Trap if the bytes at extra_urefs_ptr cannot be de-serialized as type Vec<URef>, or
if any of the extra casperlabs_types::uref::URefs are invalid in the current
context.
Arguments
value_ptr: pointer to bytes representing the value to return to the callervalue_size: size of the value (in bytes)
