FINDMSB(3G)                     [FIXME: manual]                    FINDMSB(3G)

NAME
       findMSB - find the index of the most significant bit set to 1 in an
       integer

DECLARATION
       genIType findMSB(genIType value);

       genIType findMSB(genUType value);

PARAMETERS
       value
           Specifies the value whose bits to scan.

DESCRIPTION
       findMSB returns the bit number of the most significant bit that is set
       to 1 in the binary representation of value. For positive integers, the
       result will be the bit number of the most significant bit that is set
       to 1. For negative integers, the result will be the bit number of the
       most significant bit set to 0. For a value of zero or negative 1, -1
       will be returned.
