7.6.2.2.13 Write H1 system values
#include <H1Def.h>
unsigned short WENTRY_C H1SetzeStandardwerte(H1_INITVALUES
W_Pointer init, int nKarte=0)
You can change the H1 standard values by means of this function.
Parameters
init
pointer to a memory area containing the new system values.
nKarte
adapter number (0 - 3), default=0. This is a default parameter that may
not be required.
Returns
0
H1_NO_SLOT
H1_NO_DRIVER
H1_NO_ADAPTER
Note
These settings affect all connections. Should the H1 standard values be altered buy
means of H1SetzeStandardwerte on a running system, then the revised parameters
will be used immediately. The result may be that one connection operates with both,
old and new parameters.
H1 system values
Window sizes
MaxCredit Maximum window size. Permanently 0.
MinCredit Minimum window size. Permanently 0.
