BN_add_word(3) OpenSSL BN_add_word(3)NAME
BN_add_word, BN_sub_word, BN_mul_word, BN_div_word, BN_mod_word - arithmetic functions on BIGNUMs with integers
SYNOPSIS
#include <openssl/bn.h>
int BN_add_word(BIGNUM *a, BN_ULONG w);
int BN_sub_word(BIGNUM *a, BN_ULONG w);
int BN_mul_word(BIGNUM *a, BN_ULONG w);
BN_ULONG BN_div_word(BIGNUM *a, BN_ULONG w);
BN_ULONG BN_mod_word(const BIGNUM *a, BN_ULONG w);
DESCRIPTION
These functions perform arithmetic operations on BIGNUMs with unsigned integers. They are much more efficient than the normal BIGNUM arith-
metic operations.
BN_add_word() adds w to a ("a+=w").
BN_sub_word() subtracts w from a ("a-=w").
BN_mul_word() multiplies a and w ("a*=b").
BN_div_word() divides a by w ("a/=w") and returns the remainder.
BN_mod_word() returns the remainder of a divided by w ("a%m").
For BN_div_word() and BN_mod_word(), w must not be 0.
RETURN VALUES
BN_add_word(), BN_sub_word() and BN_mul_word() return 1 for success, 0 on error. The error codes can be obtained by ERR_get_error(3).
BN_mod_word() and BN_div_word() return a%w.

BN_add_word() and BN_mod_word() are available in all versions of SSLeay and OpenSSL. BN_div_word() was added in SSLeay 0.8, and
BN_sub_word() and BN_mul_word() in SSLeay 0.9.0.

These functions perform arithmetic operations on BIGNUMs with unsigned integers. They are much more efficient than the normal BIGNUM arith-

BN_add_word() adds w to a (a+=w).
BN_sub_word() subtracts w from a (a-=w).

BN_div_word() divides a by w (a/=w) and returns the remainder.
BN_mod_word() returns the remainder of a divided by w (a%w).

RETURN VALUES
BN_add_word(), BN_sub_word() and BN_mul_word() return 1 for success, 0 on error. The error codes can be obtained by ERR_get_error(3).
BN_mod_word() and BN_div_word() return a%w on success and (BN_ULONG)-1 if an error occurred.

Before 0.9.8a the return value for BN_div_word() and BN_mod_word() in case of an error was 0.

Hi,
What is installation package and how to create it?
When we run:
in AIX:
installp package1
or
in Linux
rpm -ivh mypackage
What is package1 or mypackage in the abov examples and how to create them and deploy them?
I hope my question is clear enough.
Thank you (2 Replies)
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

After the success of the jq - tool for parsing and manipulating JSON-Data someone wrote a tool called yq, which aims to be the same for YAML, what jq is for JSON. Seems to work fine. I'll definitely give it a chance in future.
