* Name: strerror_r
|
|
*
|
|
* Description:
|
|
* The strerror_r() function is similar to strerror(), but is thread safe.
|
|
* It returns the error string in the user-supplied buffer 'buf' of length
|
|
* 'buflen'.
|
|
*
|
|
* Returned Value:
|
|
* strerror_r() returns 0 on success. On error, a (positive) error number is
|
|
* returned.
|
|
*
|
|
* Portability:
|
|
* Specified in POSIX.1-2001
|
