Word32 L_shl(Word32 lval2shft, Word16 s_shftamount)
Example
long result, l = 0x12345678;
short s2 = 1;
result = L_shl(l,s2);
// Expected value of result: 0x2468ACF0
L_shlftNs
Arithmetic shift of 32-bit value by a specified shift amount. If the shift count is
positive, a left shift is performed. Otherwise, a right shift is performed. Saturation does
not occur during a left shift.
NOTE
Ignores upper N-5 bits of s_shftamount except the sign bit (MSB).
