+.SH DESCRIPTION
+.IX Header "DESCRIPTION"
+These methods are currently unused, and as such, no replacement methods are
+required or planned.
+.PP
+OpenSSL has state that should be reset when a process forks. For example,
+the entropy pool used to generate random numbers (and therefore encryption
+keys) should not be shared across multiple programs.
+The \fBOPENSSL_fork_prepare()\fR, \fBOPENSSL_fork_parent()\fR, and \fBOPENSSL_fork_child()\fR
+functions are used to reset this internal state.
+.PP
+Platforms without \fBfork\fR\|(2) will probably not need to use these functions.
+Platforms with \fBfork\fR\|(2) but without \fBpthread_atfork\fR\|(3) will probably need
+to call them manually, as described in the following paragraph.  Platforms
+such as Linux that have both functions will normally not need to call these
+functions as the OpenSSL library will do so automatically.
+.PP
+\&\fBOPENSSL_init_crypto\fR\|(3) will register these functions with the appropriate
+handler, when the \fBOPENSSL_INIT_ATFORK\fR flag is used. For other
+applications, these functions can be called directly. They should be used
+according to the calling sequence described by the \fBpthread_atfork\fR\|(3)
+documentation, which is summarized here.  \fBOPENSSL_fork_prepare()\fR should
+be called before a \fBfork()\fR is done.  After the \fBfork()\fR returns, the parent
+process should call \fBOPENSSL_fork_parent()\fR and the child process should
+call \fBOPENSSL_fork_child()\fR.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fBOPENSSL_fork_prepare()\fR, \fBOPENSSL_fork_parent()\fR and \fBOPENSSL_fork_child()\fR do not
+return values.
