NAME
remctl_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. SEE ALSO

NAME
remctl_new - Create a new remctl client SYNOPSIS
#include <remctl.h> struct remctl *remctl_new(void); DESCRIPTION
remctl_new() creates a new remctl client. The resulting remctl struct is opaque from the perspective of the caller, but should be the first argument to all subsequent calls into the remctl API. Normally, the next call after remctl_new() would be remctl_open() to connect to a remote server. The resulting struct should be freed by calling remctl_close(). RETURN VALUE
remctl_new() returns a pointer to an opaque remctl struct on success and NULL on failure. If it returns NULL, errno will be set to an appropriate error code (normally ENOMEM). SEE ALSO
