Since dynamic memory allocation to create B<BIGNUM>s -is rather expensive when used in conjunction with repeated subroutine -calls, the B<BN_CTX> structure is used. - -BN_CTX_new() allocates and initializes a B<BN_CTX> -structure. - -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> -may be freed by BN_CTX_free(). - -BN_CTX_init() (deprecated) initializes an existing uninitialized B<BN_CTX>. -This should not be used for new programs. Use BN_CTX_new() instead. - -=head1 RETURN VALUES - -BN_CTX_new() returns a pointer to the B<BN_CTX>. If the allocation fails, -it returns B<NULL> and sets an error code that can be obtained by -L<ERR_get_error(3)|ERR_get_error(3)>. - -BN_CTX_init() and BN_CTX_free() have no return values. - -=head1 SEE ALSO - -L<bn(3)|bn(3)>, L<ERR_get_error(3)|ERR_get_error(3)>, L<BN_add(3)|BN_add(3)>, -L<BN_CTX_start(3)|BN_CTX_start(3)> - -=head1 HISTORY - -BN_CTX_new() and BN_CTX_free() are available in all versions on SSLeay -and OpenSSL. BN_CTX_init() was added in SSLeay 0.9.1b. - -=cut |
