Typical error codes when using the Apple SSL implementation.
comm
The apple-err-ssl-… constants are the typical error codes that you may get when using the Apple SSL implmentation. The error codes come from the underlying macOS implementation of SSL. The error code can be found using the reader ssl-condition-ssl-code on a ssl-condition that is signaled when an error is detected.
The following table lists the constant, the matching variable in C, the actual value, and the message associated with each variable:
| Lisp constant | C name | Value | Associated message |
|---|---|---|---|
|
| -9800 | SSL protocol error |
|
| -9801 | Cipher Suite negotiation failure |
|

|
| -9843 | peer host name mismatch |
|
| -9844 | peer dropped connection before responding |
|
| -9845 | decryption failure |

apple-err-ssl-record-overflow is what you typicaly get when the peer does not use SSL.
