Syntax

#include <prerror.h>

Returns

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

Description

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.
