19These functions are used to obtain temporary B<BIGNUM> variables from
|
20a B<BN_CTX> in order to save the overhead of repeatedly creating and
| 20a B<BN_CTX> (which can been created by using L<BN_CTX_new(3)|BN_CTX_new(3)>)
21in order to save the overhead of repeatedly creating and
|
21freeing B<BIGNUM>s in functions that are called from inside a loop.
22
23A function must call BN_CTX_start() first. Then, BN_CTX_get() may be
24called repeatedly to obtain temporary B<BIGNUM>s. All BN_CTX_get()
25calls must be made before calling any other functions that use the
26B<ctx> as an argument.
27
28Finally, BN_CTX_end() must be called before returning from the function.
