- modbus_strerror(3)
- =================
- 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
- -------
- .Display an error message when a Modbus connection cannot be established
- [source,c]
- -------------------
- if (modbus_connect(ctx) == -1) {
- fprintf(stderr, "Connection failed: %s\n", modbus_strerror(errno));
- abort();
- }
