Returns the current thread's last set OS-specific error code.


#include <prerror.h>

PRInt32 PR_GetOSError(void)


The value returned is a 32-bit signed number. Its interpretation is left to the caller.


Used for platform-specific code that requires the underlying OS error. For portability, clients should not create dependencies on the values of OS-specific error codes. However, this information is preserved, along with a platform neutral error code, on a per thread basis. It is most useful during development.
