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
Displaying 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();
}
