BN_CTX_new(3SSL) OpenSSL BN_CTX_new(3SSL)
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 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.
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 allocation 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.

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.
