DESCRIPTIONERR_load_crypto_strings() registers the error strings for
all libcrypto functions. SSL_load_error_strings() does
the same, but also registers the libssl error
strings.
One of these functions should be called before generating
textual error messages. However, this is not required when memory
usage is an issue.
ERR_free_strings() frees all previously loaded error strings.
RETURN VALUESERR_load_crypto_strings(), SSL_load_error_strings() and ERR_free_strings()
return no values. SEE ALSOerr(3) , ERR_error_string(3) HISTORYERR_load_error_strings(), SSL_load_error_strings() and ERR_free_strings()
are available in all versions of SSLeay and OpenSSL.
