C

TCPIP_MAC_RES TCPIP_MAC_RegisterStatisticsGet(
    DRV_HANDLE hMac, 
    TCPIP_MAC_STATISTICS_REG_ENTRY* pRegEntries, 
    int nEntries, 
    int* pHwEntries
);

Description

This function will get the current value of the statistic registers maintained by the MAC hardware.

Precondtions

TCPIP_MAC_Initialize() should have been called. TCPIP_MAC_Open() should have been called to obtain a valid handle.

Parameters

hMac	Handle identifying the MAC driver client.
pRegStatistics	Pointer to a pRegEntries that will receive the current hardware statistics registers values. Can be 0, if only the number of supported hardware registers is requested.
nEntries	Provides the number of TCPIP_MAC_STATISTICS_REG_ENTRY structures present in pRegEntries Can be 0, if only the number of supported hardware registers is requested The register entries structures will be filled by the driver, up to the supported hardware registers.
pHwEntries	Pointer to an address to store the number of the statistics registers that the hardware supports It is updated by the driver. Can be 0 if not needed.
