Name
bit_rot_left
Synopsis
void bit_rot_left(unsigned char *bits, intsize, intcount);
Return Value
None.
Description
Rotates the buffer bits,
containing size bits, to the left
count bits. After the operation, the
leftmost count bits become the
count rightmost bits in the buffer, and
all other bits are shifted accordingly.
Complexity
O (n β), where n is the number of bits rotated to the left and β is the number of bits in the buffer.
