Macro Definition Documentation

SYSTEM_ERROR_BIT

#define SYSTEM_ERROR_BIT   30

para_error

This bit indicates whether a number is considered a system error number If yes, the system errno is just the result of clearing this bit from the given number.

OSL_ERROR_BIT

#define OSL_ERROR_BIT   29

Like SYSTEM_ERROR_BIT, but for errors from the osl library.

LLS_ERROR_BIT

#define LLS_ERROR_BIT   28

Like SYSTEM_ERROR_BIT, but for errors from the lopsub library.

IS_SYSTEM_ERROR

#define IS_SYSTEM_ERROR

(

num

)

(!!((num) & (1 << SYSTEM_ERROR_BIT)))

Check whether the system error bit is set.

IS_OSL_ERROR

#define IS_OSL_ERROR

(

num

)

(!!((num) & (1 << OSL_ERROR_BIT)))

Check whether the osl error bit is set.

IS_LLS_ERROR

#define IS_LLS_ERROR

(

num

)

(!!((num) & (1 << LLS_ERROR_BIT)))

Check whether the lopsub error bit is set.

ERRNO_TO_PARA_ERROR

#define ERRNO_TO_PARA_ERROR

(

num

)

((num) | (1 << SYSTEM_ERROR_BIT))

Set the system error bit for the given number.

OSL_ERRNO_TO_PARA_ERROR

#define OSL_ERRNO_TO_PARA_ERROR

(

num

)

((num) | (1 << OSL_ERROR_BIT))

Set the osl error bit for the given number.

LLS_ERRNO_TO_PARA_ERROR

#define LLS_ERRNO_TO_PARA_ERROR

(

num

)

((num) | (1 << LLS_ERROR_BIT))

Set the lopsub error bit for the error code.

Function Documentation

para_strerror()

_static_inline_ const char* para_strerror

(

int

num

)

Paraslash's version of strerror(3).

Parameters

num	The error number.

Returns

The error text of num.

Referenced by afs_error(), check_receiver_arg(), generic_com_on(), send_strerror(), task_notify(), and task_reap().

osl()

_static_inline_ int osl

(

int

ret

)

Wrapper for osl library calls.

Parameters

ret	The return value of an osl library function.

This should be used for all calls to osl functions that return an osl error code. It changes the return value appropriately so that it can be used for printing the correct error message with para_strerror().

Returns

ret if ret >= 0, a paraslash error code otherwise.

lls()

_static_inline_ int lls

(

int

ret

)

Wrapper for lopsub library calls.

Parameters

ret	See osl().

Returns

See osl().
