modbus_strerror()					     modbus_strerror()

Name
       modbus_strerror - return	the error message

Synopsis
       const char *modbus_strerror(int errnum);

Description
       The  modbus_strerror() function shall return a pointer to an error mes-
       sage string corresponding to the	error number specified by  the	errnum
       argument.  As libmodbus defines additional error	numbers	over and above
       those defined by	the operating system,  applications  should  use  mod-
       bus_strerror() in preference to the standard strerror() function.

Return value
       The  modbus_strerror() function shall return a pointer to an error mes-
       sage string.

Errors
       No errors are defined.

Example
       Display an error	message	when a Modbus connection cannot	be established

       if (modbus_connect(ctx) == -1) {
	   fprintf(stderr, "Connection failed: %s\n", modbus_strerror(errno));
	   abort();
       }
