Hi,
If i reuse a BIGNUM created with BN_new() without freeing it first will i cause a memory leak? does the BIGNUM dynamically allocate memory each time it is used by certain functions?
for example i create BIGNUM * tempBN=BN_new();
i might make a call to BN_bin2bn (char1,len,tempBN);
i might make a similar call later BN_bin2bn(char2,len2,tempBN);
is this reuse of a big number like this going to cause
a memory leak?? Is tempBN reusing the same memory or is it allocating
new memory. How is it working internally?
Is there a faq/sample code/tips on how to use the BN library?
At the moment i allocate a lot of BIGNUM's using BN_new() at the start of the program. I then reuse these BIGNUM's over and over and over throughout multiple runs of a long computation.
I had thought that by creating them at the start of
the program and then just reusing them that i wouldn't
be repeatedly dynamically allocating memory and not
freeing it. but now i'm not so sure. Musn't the BIGNUM be
reallocating memory every time i use it otherwise how does it know what size to make itself initially?
How should i do this type of thing properly?
thanks for any help.
