BitVecRemoveLast

BitVecRemoveLast

Description

Remove the last occurrence of a specific bit value.

Parameters

Name Direction Description
bv in,out Bitvector to remove from.
value in Bit value to find and remove (true or false).

Usage example (from documentation) 

  bool found = BitVecRemoveLast(&flags, false);

Success

Returns true. The last bit equal to value has been removed; bitvector length shrinks by one; bits after the removed position have shifted left by one (if any).

Failure

Returns false when no bit equal to value was found. The bitvector is unchanged.
