This function can be used to get a system diagnostic message.The errno argument value may be any error code as defined in the header file,or may be the global errno variable.The global errno variable is set whenever a system API is called and its value is zero if the API execution is successful,nonzero otherwise.The return character string is read-only and should not be de-allocated by users.
