remctl_error - 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().
remctl_error() returns either the previous error or the constant string "No error". It will never return NULL.
remctl_new(3), remctl_open(3), remctl_command(3), remctl_commandv(3), remctl_output(3) The current version of the remctl library and complete details of the remctl protocol are available from its web page at <http://www.eyrie.org/~eagle/software/remctl/>.
