BN_CTX_new(3)							 BN_CTX_new(3)

NAME
       BN_CTX_new,  BN_CTX_init, BN_CTX_free - Allocate and free BN_CTX struc‐
       tures

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 variables  used  by
       library functions. Since dynamic memory allocation to create BIGNUMs is
       rather expensive when used  in  conjunction  with  repeated  subroutine
       calls, the BN_CTX structure is used.

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

       The  BN_CTX_free()  function frees the components of the BN_CTX, and if
       it  was	created	 by  BN_CTX_new(),  also  the  structure  itself.   If
       BN_CTX_start() has been used on the BN_CTX, BN_CTX_end() 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 allocation	fails,
       it  returns  NULL  and  sets  an	 error	code  that  can be obtained by
       ERR_get_error().

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

HISTORY
       The BN_CTX_new() and BN_CTX_free() functions are available in all  ver‐
       sions  on  SSLeay  and OpenSSL. The BN_CTX_init() function was added in
       SSLeay 0.9.1b.
