Function pamoja_audit_log_append 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn pamoja_audit_log_append(
    log: *mut PamojaAuditLog,
    payload: *const u8,
    payload_len: usize,
) -> *mut PamojaAuditEntry

Appends a payload to a log, signing it and chaining it onto the last entry.

Arguments

• log - the log to append to.
• payload - the record to store.
• payload_len - the length of payload in bytes.

Returns

A handle to the new entry, which the caller must release with pamoja_audit_entry_free, or null on failure.

Safety

log must be a live handle from pamoja_audit_log_new or pamoja_audit_log_resume, and payload must point to at least payload_len readable bytes, or be null when payload_len is 0.
