If bits is non null, it should have enough size to hold the parameters size in bits. For RSA the bits returned is the modulus. For DSA the bits returned are of the public exponent. .SH "RETURNS" a member of the \fBgnutls_pk_algorithm_t\fP enumeration on success, or GNUTLS_PK_UNKNOWN on error. .SH "SINCE" 2.4.0 .SH "REPORTING BUGS" Report bugs to . .br Home page: http://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2017 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.
