Decoding OSStatus values

2008-10-15 Thread Richard Dearlove 
Is there an easy way to decode the values from OSStatus.  I have this  
#define that I copied from another project but it isnt really helping..


This gives me an error such as  Error: \316\377\377\377

#define checkStatus( err) \
if(err) {\
printf(Error: %s -  %s: %d\n, (char *)err,__FILE__, __LINE__);\
fflush(stdout);\
return err; \
}

cheers

An OSStatus is not an OSType (FourCharCode).

OSStatus can be any value and does not generaly contains readable  
characters.


To get an idea about what an OSStatus represent, you can use thoses 2  
functions (from CarbonCore):


const char* GetMacOSStatusErrorString(OSStatus err);
const char* GetMacOSStatusCommentString(OSStatus err);
