144 .IX Header "SYNOPSIS"
146 \& #include <openssl/dsa.h>
148 \& DSA* DSA_new(void);
150 \& void DSA_free(DSA *dsa);
153 .IX Header "DESCRIPTION"
154 \&\fIDSA_new()\fR allocates and initializes a \fB\s-1DSA\s0\fR structure. It is equivalent to
155 calling DSA_new_method(\s-1NULL\s0).
157 \&\fIDSA_free()\fR frees the \fB\s-1DSA\s0\fR structure and its components. The values are
158 erased before the memory is returned to the system.
160 .IX Header "RETURN VALUES"
161 If the allocation fails, \fIDSA_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
162 code that can be obtained by
163 \&\fIERR_get_error\fR\|(3). Otherwise it returns a pointer
164 to the newly allocated structure.
166 \&\fIDSA_free()\fR returns no value.
168 .IX Header "SEE ALSO"
