remctl_error: Retrieve the error from a failed remctl operation
remctl_error - Retrieve the error from a failed remctl operation
DESCRIPTIONremctl_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 VALUEremctl_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.
