Appendix C, 4D Internet Commands Error Codes
version 2004 (Modified)
All 4D Internet Commands (with the exception of IT_ErrorText & IT_Version) return an integer value as the result of the function. This integer contains any error number which the command needs to convey back to the 4D database. If a command is successful, a zero will be returned. The source of an error number can usually be determined by the range of values which the error falls within. The following table provides an index to the most likely creator of an error in any given range:
| Error Number | Generated by |
| Error < Zero | Operating System Error or WinSock network layer |
| Zero | No Error |
| Error 1 -> 61 | BSD network layer |
| Error >= 10000 | 4D Internet Commands Error |
