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_init() initializes an existing uninitialized +B<BN_CTX>. + +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(). + + +=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 |
