int error is a GnuTLS error code, a negative error code
ОПИСАНИЕ
If a GnuTLS function returns a negative error code you may feed
that value to this function to see if the error condition is
fatal to a TLS session (i.e., must be terminated).
Note that you may also want to check the error code manually,
since some non-fatal errors to the protocol (such as a warning
alert or a rehandshake request) may be fatal for your program.
This function is only useful if you are dealing with errors from
functions that relate to a TLS session (e.g., record layer or
handshake layer handling functions).
ЗНАЧЕНИЕ, ВОЗВРАЩАЕМОЕ ФУНКЦИЕЙ
Non-zero value on fatal errors or zero on non-fatal.
