NAME

6       remctl_error - Retrieve the error from a failed remctl operation
7

SYNOPSIS

9       #include <remctl.h>
10
11       const char *remctl_error(struct remctl *r);
12

DESCRIPTION

14       remctl_error() returns the error from a previously failed remctl
15       operation.  Its only argument is a remctl struct as returned by
16       remctl_new().  If the previous remctl operation was successful, returns
17       the constant string "No error".
18
19       The caller may not modify the returned string.  The string may even be
20       stored in read-only memory and attempting to modify it may cause a
21       memory fault.  The returned pointer will be invalidated by the next
22       call to any remctl API function with the same client object, other than
23       remctl_error().
24

RETURN VALUE

26       remctl_error() returns either the previous error or the constant string
27       "No error".  It will never return NULL.
28

COMPATIBILITY

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