No. Basically, you need to use a sequence like this:
recH = DmGetRecord ( database, index )
oldrecsize = MemHandleSize ( recH );
if ( oldrecsize != newrecsize ) {
err = MemHandleResize ( recH, newrecsize );
recH = ResizeRecord ( recH, index, newrecsize);
}
recP = MemHandleLock ( recH );
error = DmWrite ( recP, 0, bufferPointer, newrecsize );
MemHandleUnlock ( recH );
error = DmReleaseRecord ( database, index, true );
Note: this is abbreviated and contains no error checking.
