BN_CTX_start(3SSL) OpenSSL BN_CTX_start(3SSL)NAME
BN_CTX_start, BN_CTX_get, BN_CTX_end - use temporary BIGNUM variables
SYNOPSIS
#include <openssl/bn.h>
void BN_CTX_start(BN_CTX *ctx);
BIGNUM *BN_CTX_get(BN_CTX *ctx);
void BN_CTX_end(BN_CTX *ctx);
DESCRIPTION
These functions are used to obtain temporary BIGNUM variables from a BN_CTX (which can been created by using BN_CTX_new(3)) in order to
save the overhead of repeatedly creating and freeing BIGNUMs in functions that are called from inside a loop.
A function must call BN_CTX_start() first. Then, BN_CTX_get() may be called repeatedly to obtain temporary BIGNUMs. All BN_CTX_get() calls
must be made before calling any other functions that use the ctx as an argument.
Finally, BN_CTX_end() must be called before returning from the function. When BN_CTX_end() is called, the BIGNUM pointers obtained from
BN_CTX_get() become invalid.
RETURN VALUES
BN_CTX_start() and BN_CTX_end() return no values.
BN_CTX_get() returns a pointer to the BIGNUM, or NULL on error. Once BN_CTX_get() has failed, the subsequent calls will return NULL as
well, so it is sufficient to check the return value of the last BN_CTX_get() call. In case of an error, an error code is set, which can be
obtained by ERR_get_error(3).
SEE ALSO BN_CTX_new(3)HISTORY
BN_CTX_start(), BN_CTX_get() and BN_CTX_end() were added in OpenSSL 0.9.5.

What is the point of this? Whenever I close my shell it appends to the history file without adding this. I have never seen it overwrite my history file.
# When the shell exits, append to the history file instead of overwriting it

Greetings,
I'm trying to delete a file with a weird name from within Terminal on a Mac.
It's a very old file (1992) with null characters in the name: ââWord FinderÂŽ Plusâ˘.
Here are some examples of what I've tried:
12FX009:5 dpontius$ ls
ââWord FinderÂŽ Plusâ˘
12FX009:5 dpontius$ rm... (29 Replies)
