The +values are erased before the memory is returned to the system. +If the argument is NULL, nothing is done. +.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 DSA_SIG 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 \fBNULL\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" +\&\fBEVP_PKEY_new\fR\|(3), \fBEVP_PKEY_free\fR\|(3), \fBEVP_PKEY_get_bn_param\fR\|(3), +\&\fBERR_get_error\fR\|(3) +.SH COPYRIGHT +.IX Header "COPYRIGHT" +Copyright 2000\-2024 The OpenSSL Project Authors.
