Anyone here could tell me How to handle a case where 1 bit can decide the format of a 32 bit word ? Bit 0 type of data If bit 0 = 0 Bit 1-15 Real Bit 16 Timing mark Bit 17-31 Imaginary If bit 0 = 1 Bit 1-5 Real Bit 16-31 Raw data Thank you Philippe On Thursday, October 3, 2002, at 01:50 PM, nathan@gcc.gnu.org wrote: > Synopsis: Union of struct of union of struct bit field > > State-Changed-From-To: open->closed > State-Changed-By: nathan > State-Changed-When: Thu Oct 3 03:50:48 2002 > State-Changed-Why: > not a bug.

Push the one bit down into each structure. If it's at the same place in each structure, then it doesn't matter which one you access to examine it. r~ ^ permalink raw reply [flat|nested] 2+ messages in thread
