 // Use the OSSTATUS_LOG family to log messages related to errors in Mac OS X
 // system routines that report status via an OSStatus or OSErr value. It is
 // similar to the PLOG family which operates on errno, but because there is no
 // global (or thread-local) OSStatus or OSErr value, the specific error must
 // be supplied as an argument to the OSSTATUS_LOG macro. The message logged
 // will contain the symbolic constant name corresponding to the status value,
 // along with the value itself.
 //
 // OSErr is just an older 16-bit form of the newer 32-bit OSStatus. Despite
