MODBUS_STRERROR(3) Libmodbus Manual 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
if (modbus_connect(ctx) == -1) {
fprintf(stderr, "Connection failed: %s
", modbus_strerror(errno));
abort();
}
