NAMEremctl_error − Retrieve the error from a failed remctl operation

---

SYNOPSIS#include <remctl.h> const char *remctl_error(struct remctl *r);

---

DESCRIPTION​remctl_error() returns the error from a previously failed remctl operation. Its only argument is a remctl struct as returned by ​remctl_new(). If the previous remctl operation was successful, returns the constant string ‟No error”. The caller may not modify the returned string. The string may even be stored in read-only memory and attempting to modify it may cause a memory fault. The returned pointer will be invalidated by the next call to any remctl API function with the same client object, other than ​remctl_error().

---

RETURN VALUE​remctl_error() returns either the previous error or the constant string ​‟No error”. It will never return NULL.

---

COMPATIBILITYThis interface has been provided by the remctl client library since its initial release in version 2.0.
