remctl_error - Man Page

Retrieve the error from a failed remctl operation


#include <remctl.h>

const char *remctl_error(struct remctl *r);


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.


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