PDFlibErrorMessage

Error handling

Description

PDFlibErrorMessage maps a numeric error code, such as the value reported by LastErrorCode, to its human-readable English message

The codes fall into documented families: 0 is success, 1xx covers legacy encryption parameters and request validation, 3xx covers save and write failures, 4xx covers load and authentication failures, and 5xx covers generic, render and IO failures

The LoggerDemo logs PDFlibErrorMessage(403) alongside a simulated encrypted-document scenario to show translated logging

Syntax

Delphi

Function PDFlibErrorMessage(Code: Integer): WideString;

Fields

Code	The numeric error code to translate

Return value

The message text for the code, for example 403 yields Encrypted document requires password

Remarks

Unknown codes fall back to a generic message, so the function is safe to call on any integer

Use PDFlibErrorCategory when the caller needs the code family rather than the text
