144 DSA_SIG_new, DSA_SIG_free \- allocate and free DSA signature objects
148 .IX Header "SYNOPSIS"
150 \& #include <openssl/dsa.h>
152 \& DSA_SIG *DSA_SIG_new(void);
154 \& void DSA_SIG_free(DSA_SIG *a);
157 .IX Header "DESCRIPTION"
158 \&\fIDSA_SIG_new()\fR allocates and initializes a \fB\s-1DSA_SIG\s0\fR structure.
160 \&\fIDSA_SIG_free()\fR frees the \fB\s-1DSA_SIG\s0\fR structure and its components. The
161 values are erased before the memory is returned to the system.
163 .IX Header "RETURN VALUES"
164 If the allocation fails, \fIDSA_SIG_new()\fR returns \fB\s-1NULL\s0\fR and sets an
165 error code that can be obtained by
166 \&\fIERR_get_error\fR\|(3). Otherwise it returns a pointer
167 to the newly allocated structure.
169 \&\fIDSA_SIG_free()\fR returns no value.
171 .IX Header "SEE ALSO"
172 \&\fIopenssl_dsa\fR\|(3), \fIERR_get_error\fR\|(3),
173 \&\fIDSA_do_sign\fR\|(3)
176 \&\fIDSA_SIG_new()\fR and \fIDSA_SIG_free()\fR were added in OpenSSL 0.9.3.
