+.SH "DESCRIPTION"
+.IX Header "DESCRIPTION"
+These functions are used to obtain temporary \fB\s-1BIGNUM\s0\fR variables from
+a \fB\s-1BN_CTX\s0\fR (which can been created by using \fIBN_CTX_new\fR\|(3))
+in order to save the overhead of repeatedly creating and
+freeing \fB\s-1BIGNUM\s0\fRs in functions that are called from inside a loop.
+.PP
+A function must call \fIBN_CTX_start()\fR first. Then, \fIBN_CTX_get()\fR may be
+called repeatedly to obtain temporary \fB\s-1BIGNUM\s0\fRs. All \fIBN_CTX_get()\fR
+calls must be made before calling any other functions that use the
+\&\fBctx\fR as an argument.
+.PP
+Finally, \fIBN_CTX_end()\fR must be called before returning from the function.
+When \fIBN_CTX_end()\fR is called, the \fB\s-1BIGNUM\s0\fR pointers obtained from
+\&\fIBN_CTX_get()\fR become invalid.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fIBN_CTX_start()\fR and \fIBN_CTX_end()\fR return no values.
+.PP
+\&\fIBN_CTX_get()\fR returns a pointer to the \fB\s-1BIGNUM\s0\fR, or \fB\s-1NULL\s0\fR on error.
+Once \fIBN_CTX_get()\fR has failed, the subsequent calls will return \fB\s-1NULL\s0\fR
+as well, so it is sufficient to check the return value of the last
+\&\fIBN_CTX_get()\fR call. In case of an error, an error code is set, which
+can be obtained by \fIERR_get_error\fR\|(3).
