+// 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 |
+// the name, OSSTATUS_LOG can be used equally well for OSStatus and OSErr. |
