BN_CTX_NEW(3)		     OpenSSL		    BN_CTX_NEW(3)

NAME
     BN_CTX_new, BN_CTX_init, BN_CTX_free - allocate and free
     BN_CTX structures

SYNOPSIS
      #include <openssl/bn.h>

      BN_CTX *BN_CTX_new(void);

      void BN_CTX_init(BN_CTX *c);

      void BN_CTX_free(BN_CTX *c);

DESCRIPTION
     A BN_CTX is a structure that holds BIGNUM temporary vari-
     ables used by library functions. Since dynamic memory allo-
     cation to create BIGNUMs is rather expensive when used in
     conjunction with repeated subroutine calls, the BN_CTX
     structure is used.

     BN_CTX_new() allocates and initializes a BN_CTX structure.
     BN_CTX_init() initializes an existing uninitialized BN_CTX.

     BN_CTX_free() frees the components of the BN_CTX, and if it
     was created by BN_CTX_new(), also the structure itself. If
     BN_CTX_start(3) has been used on the BN_CTX, BN_CTX_end(3)
     must be called before the BN_CTX may be freed by
     BN_CTX_free().

RETURN VALUES
     BN_CTX_new() returns a pointer to the BN_CTX. If the alloca-
     tion fails, it returns NULL and sets an error code that can
     be obtained by ERR_get_error(3).

     BN_CTX_init() and BN_CTX_free() have no return values.

SEE ALSO
     bn(3), ERR_get_error(3), BN_add(3), BN_CTX_start(3)

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.
