Since 3.6.0 this function never returns a negative error code. Error cases and unknown/unsupported signature algorithms are mapped to \fBGNUTLS_SIGN_UNKNOWN\fP. .SH "RETURNS" a \fBgnutls_sign_algorithm_t\fP value .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2021 Free Software Foundation, Inc., and others. .br Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
