BN_CTX_free() frees the components of the B<BN_CTX>, and if it was
created by BN_CTX_new(), also the structure itself.
-If L<BN_CTX_start(3)|BN_CTX_start(3)> has been used on the B<BN_CTX>,
-L<BN_CTX_end(3)|BN_CTX_end(3)> must be called before the B<BN_CTX>
+If L<BN_CTX_start(3)> has been used on the B<BN_CTX>,
+L<BN_CTX_end(3)> must be called before the B<BN_CTX>
may be freed by BN_CTX_free().
If B<c> is NULL, nothing is done.
BN_CTX_new() and BN_CTX_secure_new() return a pointer to the B<BN_CTX>.
If the allocation fails,
they return B<NULL> and sets an error code that can be obtained by
-L<ERR_get_error(3)|ERR_get_error(3)>.
+L<ERR_get_error(3)>.
BN_CTX_free() has no return values.
