.SH NAME
DSA_SIG_new, DSA_SIG_free \- allocate and free DSA signature objects
.SH SYNOPSIS
.IX Header "SYNOPSIS"
.Vb 1
\& #include <openssl/dsa.h>

\& DSA_SIG *DSA_SIG_new(void);

.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\fBDSA_SIG_new()\fR allocates and initializes a \fBDSA_SIG\fR structure.
.PP
\&\fBDSA_SIG_free()\fR frees the \fBDSA_SIG\fR structure and its components. The
values are erased before the memory is returned to the system.
.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.
.SH "SEE ALSO"
.IX Header "SEE ALSO"
\&\fBdsa\fR\|(3), \fBERR_get_error\fR\|(3),
\&\fBDSA_do_sign\fR\|(3)
.SH HISTORY
.IX Header "HISTORY"
\&\fBDSA_SIG_new()\fR and \fBDSA_SIG_free()\fR were added in OpenSSL 0.9.3.
