It doesn't preclude them defining their own error//              return system, but this is a preferable system to use to help//              error support be as general as possible.////              We try and conform to the ANSI/POSIX error code format, namely//              starting with the character 'E'//// Usage:       #include <cyg/error/codes.h>////              Example://              //              err=myfun();//              if (err != ENOERR)//              {//                str=strerror(err);//                printf("myfun returned error: %s\n", str);//              }//              else ....////####DESCRIPTIONEND####////===========================================================================// CONFIGURATION#include <pkgconf/error.h>          // Configuration header#include <cyg/infra/cyg_type.h>     // externC// Include the error package?#ifdef CYGPKG_ERROR// TYPE DEFINITIONS// A type for error codes which may be useful to explain the purpose of// a variable or return code. It shows that it contains an error code// of the type defined belowtypedef int Cyg_ErrNo;// FUNCTION PROTOTYPES// ANSI standard strerror() function as described by ANSI chap. 7.11.6.2.// This is normally provided by <string.h>externC char *strerror( Cyg_ErrNo );// prototype for the actual implementation. Equivalent to the above, but// used internally by this product in preferenceexternC char *_strerror( Cyg_ErrNo );// CONSTANT DEFINITIONS// If adding to this list, you must also update strerror() with its text// If there is a common error of the same purpose on Unix, try and use its// name and number. If not, use one above 200 to prevent future conflicts//// Do not use negative numbers, so that functions can return positive on// success and -ESOMETHING on error, and it all works consistently.#define ENOERR           0     // No error#define EPERM            1     // Not permitted#define ENOENT           2     // No such entity#define ESRCH            3     // No such process#define EINTR            4     // Operation interrupted#define EIO              5     // I/O error#define EBADF            9     // Bad file handle#define EAGAIN           11    // Try again later#define EWOULDBLOCK      EAGAIN#define ENOMEM           12    // Out of memory#define EBUSY            16    // Resource busy#define ENODEV           19    // No such device#define EINVAL           22    // Invalid argument#define EMFILE           24    // Too many open files#define EDOM             33    // Argument to math function outside valid                               // domain#define ERANGE           34    // Math result cannot be represented#define ENOSYS           38    // Function not implemented#define EEOF             200   // End of file reached#define ENOSUPP          201   // Operation not supported#define EDEVNOSUPP       202   // Device does not support this operation#endif // ifdef CYGPKG_ERROR#endif // CYGONCE_ERROR_CODES_H multiple inclusion protection// EOF codes.h
