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\n", modbus_strerror(errno));
abort();
}
