  150. \&\fIDSA_new()\fR allocates and initializes a \fB\s-1DSA\s0\fR structure. It is equivalent to

  153. \&\fIDSA_free()\fR frees the \fB\s-1DSA\s0\fR structure and its components. The values are

  157. If the allocation fails, \fIDSA_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
  158. code that can be obtained by
  159. \&\fIERR_get_error\fR\|(3). Otherwise it returns a pointer
  160. to the newly allocated structure.
