The values are erased before the memory is returned to the system. .PP \&\fBDSA_SIG_get0()\fR returns internal pointers to the \fBr\fR and \fBs\fR values contained in \fBsig\fR. .PP The \fBr\fR and \fBs\fR values can be set by calling \fBDSA_SIG_set0()\fR and passing the new values for \fBr\fR and \fBs\fR as parameters to the function. Calling this function transfers the memory management of the values to the \s-1DSA_SIG\s0 object, and therefore the values that have been passed in should not be freed directly after this function has been called. .SH "RETURN VALUES" .IX Header "RETURN VALUES" If the allocation fails, \fBDSA_SIG_new()\fR returns \fB\s-1NULL\s0\fR and sets an error code that can be obtained by \&\fBERR_get_error\fR\|(3). Otherwise it returns a pointer to the newly allocated structure. .PP \&\fBDSA_SIG_free()\fR returns no value. .PP \&\fBDSA_SIG_set0()\fR returns 1 on success or 0 on failure. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBDSA_new\fR\|(3), \fBERR_get_error\fR\|(3), \&\fBDSA_do_sign\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2000\-2016 The OpenSSL Project Authors.
