| Hi, Is there a reason why the Csound AuxAlloc function return value is void? Would it be possible to return the pointer to the auxp member of the AUXCH struct? I don’t think this would break anything that is already using it, and it could also save a line of code each time it is used, I just noticed in my hdf5 plugin I have stuff like this: csound->AuxAlloc(csound, sizeof(hsize_t), &dataset->chunkDimensionsMemory); dataset->chunkDimensions = dataset->chunkDimensionsMemory.auxp; csound->AuxAlloc(csound, sizeof(hsize_t), &dataset->maxDimensionsMemory); dataset->maxDimensions = dataset->maxDimensionsMemory.auxp; csound->AuxAlloc(csound, sizeof(hsize_t), &dataset->datasetSizeMemory); dataset->datasetSize = dataset->datasetSizeMemory.auxp; csound->AuxAlloc(csound, sizeof(hsize_t), &dataset->offsetMemory); dataset->offset = dataset->offsetMemory.auxp; Which could be halved in line count. Thanks Ed |

Or you coul do 1 call to AxAlloc ad then 4 assignments si qiker On Thu, 3 Aug 2017, Ed Costello wrote: > Hi, > Is there a reason why the Csound AuxAlloc function return value is void?

I cannot think of a good reason except it changes the API On Thu, 3 Aug 2017, jpff wrote: > Or you could do 1 call to AuxAlloc and then 4 assignments is quicker > > > On Thu, 3 Aug 2017, Ed Costello wrote: > >> Hi, >> Is there a reason why the Csound AuxAlloc function return value is void? >> Would >> it be possible to return the pointer to the auxp member of the AUXCH >> struct?
