Function patch_seq_file_append 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn patch_seq_file_append(stack: Stack) -> Stack

Append string to file (creates if doesn’t exist)

Stack effect: ( String String – Bool )

Takes content and path, appends content to file. Creates the file if it doesn’t exist. Returns true on success, false on failure.

Safety

• stack must be a valid, non-null stack pointer
• Top of stack must be path (String), second must be content (String)
