If the data provided are NULL then the data in the encapsulatedContent field will be used instead. .SH "RETURNS" On success, \fBGNUTLS_E_SUCCESS\fP (0) is returned, otherwise a negative error value. A verification error results to a \fBGNUTLS_E_PK_SIG_VERIFY_FAILED\fP and the lack of encapsulated data to verify to a \fBGNUTLS_E_REQUESTED_DATA_NOT_AVAILABLE\fP. .SH "SINCE" 3.4.2 .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2023 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.
