unsigned long _lrotl(unsigned long a, int shift);

Intel Description

Shift the bits of unsigned long integer “a” left by the number of bits specified in “shift”, rotating the most-significant bit to the least-significant bit location, and store the unsigned result in “dst”.

Intel Implementation Psudeo-Code

dst := a
count := shift AND (size - 1)
DO WHILE (count > 0)
        tmp[0] := dst[size - 1]
