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 message 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
       modbus_strerror() in preference to the standard strerror() function.

RETURN VALUE
       The modbus_strerror() function shall return a pointer to an error message string.

ERRORS
       No errors are defined.

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