BN_NEW(3)		     OpenSSL			BN_NEW(3)

NAME
     BN_new, BN_init, BN_clear, BN_free, BN_clear_free - allocate
     and free BIGNUMs

SYNOPSIS
      #include <openssl/bn.h>

      BIGNUM *BN_new(void);

      void BN_init(BIGNUM *);

      void BN_clear(BIGNUM *a);

      void BN_free(BIGNUM *a);

      void BN_clear_free(BIGNUM *a);

DESCRIPTION
     BN_new() allocated and initializes a BIGNUM structure.
     BN_init() initializes an existing uninitialized BIGNUM.

     BN_clear() is used to destroy sensitive data such as keys
     when they are no longer needed. It erases the memory used by
     a and sets it to the value 0.

     BN_free() frees the components of the BIGNUM, and if it was
     created by BN_new(), also the structure itself.
     BN_clear_free() additionally overwrites the data before the
     memory is returned to the system.

RETURN VALUES
     BN_new() returns a pointer to the BIGNUM. If the allocation
     fails, it returns NULL and sets an error code that can be
     obtained by ERR_get_error(3).

     BN_init(), BN_clear(), BN_free() and BN_clear_free() have no
     return values.

SEE ALSO
     bn(3), ERR_get_error(3)

HISTORY
     BN_new(), BN_clear(), BN_free() and BN_clear_free() are
     available in all versions on SSLeay and OpenSSL.  BN_init()
     was added in SSLeay 0.9.1b.
