134 DH_new, DH_free \- allocate and free DH objects
136 .IX Header "SYNOPSIS"
138 \& #include <openssl/dh.h>
146 \& void DH_free(DH *dh);
149 .IX Header "DESCRIPTION"
150 \&\fIDH_new()\fR allocates and initializes a \fB\s-1DH\s0\fR structure.
152 \&\fIDH_free()\fR frees the \fB\s-1DH\s0\fR structure and its components. The values are
153 erased before the memory is returned to the system.
155 .IX Header "RETURN VALUES"
156 If the allocation fails, \fIDH_new()\fR returns \fB\s-1NULL\s0\fR and sets an error
157 code that can be obtained by \fIERR_get_error\fR\|(3). Otherwise it returns
158 a pointer to the newly allocated structure.
160 \&\fIDH_free()\fR returns no value.
