"NAME"
BN_add_word, BN_sub_word, BN_mul_word, BN_div_word, BN_mod_word - arithmetic
functions on BIGNUMs with integers
"SYNOPSIS"
Header "SYNOPSIS" .Vb 1
#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);

"DESCRIPTION"
Header "DESCRIPTION" These functions perform arithmetic operations on BIGNUMs with unsigned
integers. They are much more efficient than the normal \s-1BIGNUM\s0
arithmetic operations.
\fIBN_add_word() adds w to a (\*(C`a+=w\*(C').
\fIBN_sub_word() subtracts w from a (\*(C`a-=w\*(C').
\fIBN_mul_word() multiplies a and w (\*(C`a*=w\*(C').
\fIBN_div_word() divides a by w (\*(C`a/=w\*(C') and returns the remainder.
\fIBN_mod_word() returns the remainder of a divided by w (\*(C`a%w\*(C').
For BN_div_word() and BN_mod_word(), w must not be 0.
"RETURN VALUES"
Header "RETURN VALUES" \fIBN_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).
\fIBN_mod_word() and BN_div_word() return a%w on success and \fB(\s-1BN_ULONG\s0)-1 if an error occurred.
"SEE ALSO"
Header "SEE ALSO" \fIbn\|(3), ERR_get_error\|(3), BN_add\|(3)
"HISTORY"
Header "HISTORY" \fIBN_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
\fIBN_sub_word() and BN_mul_word() in SSLeay 0.9.0.
Before 0.9.8a the return value for BN_div_word() and BN_mod_word() in case of an error was 0.
