148 .IX Header "SYNOPSIS"
150 \& #include <openssl/dh.h>
154 \& void DH_free(DH *dh);
157 .IX Header "DESCRIPTION"
158 \&\fIDH_new()\fR allocates and initializes a \fB\s-1DH\s0\fR structure.
160 \&\fIDH_free()\fR frees the \fB\s-1DH\s0\fR structure and its components. The values are
161 erased before the memory is returned to the system.
163 .IX Header "RETURN VALUES"
164 If the allocation fails, \fIDH_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
165 code that can be obtained by \fIERR_get_error\fR\|(3). Otherwise it returns
166 a pointer to the newly allocated structure.
168 \&\fIDH_free()\fR returns no value.
170 .IX Header "SEE ALSO"
