Function pamoja_audit_entry_previous 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_audit_entry_previous(
    entry: *const PamojaAuditEntry,
    out_previous: *mut u8,
) -> PamojaStatus

Copies out the hash of the entry before this one.

The first entry of a chain carries all zeroes here, since nothing precedes it.

Arguments

• entry - the entry.
• out_previous - receives PAMOJA_AUDIT_DIGEST_LEN bytes.

Returns

PamojaStatus::Ok on success.

Safety

entry must be a live handle, and out_previous must point to at least PAMOJA_AUDIT_DIGEST_LEN writable bytes.
