     int      errnum,
     char    *strerrbuf,
     size_t   buflen);

Parameters

errnum: (IN) Specifies the error number to be mapped to an error message.
strerrbuf: (OUT) Points to the message string associated with the error number.

The strerror_r function maps the error number in errnum to a locale-dependent error message string and returns a pointer to it in strerrbuf.
