Changes between Initial Version and Version 1 of Ticket #60581, comment 1

initial	v1
31	31	> Do not rely on the contents of the buffer unless an error code was returned. Since 7.60.0 libcurl will initialize the contents of the error buffer to an empty string before performing the transfer. For earlier versions if an error code was returned but there was no error detail then the buffer is untouched.

33		I was using High Sierra, whose libcurl version if 7.54.0, which means it does not initialize the error buffer to the empty string. It would probably be a good idea for us to initialize it to the empty string. And later when we want to pass it to Tcl, we might want to check if it is still the empty string and if so substitute a generic error message.
