Service name:
Syntax:
EthIf_GetBufferLevel
Std_ReturnType
) uint8 uint32*
EthIf_GetBufferLevel(
SwitchIdx,
SwitchBufferLevelPtr
Service ID[hex]:
0x2a
Sync/Async:
Reentrancy:
Synchronous /Asynchronous
Non Reentrant
Parameters (in):
SwitchIdx Index of the switch within the context of the Ethernet
Switch Driver
Parameters
(inout):
None
Parameters (out):
SwitchBufferLevelPtr
Return value:
Std_ReturnType
The interpretation of this value is switch dependent
E_OK: success
E_NOT_OK: switch port could not be initialized
Description:
Reads the buffer level of the corresponding switch. Whether this buffer level is one value for the entire switch (shared memory) or one value for each port at a switch is technology dependent.

[SWS_EthIf_00203]
⌈
The function EthIf_GetBufferLevel shall read the buffer level of the currently used buffer of the switch.

[SWS_EthIf_00204]
⌈
The function EthIf_GetBufferLevel shall be pre compile time configurable On/Off by the configuration parameter: EthIfGetBufferLevelApi.

⌈
If default error detection is enabled: the function shall check that the service EthIf_Init was previously called. If the check fails, the function shall raise the default error
ETHIF_E_NOT_INITIALIZED.
