CM_Get_Res_Des_Data_Size function (cfgmgr32.h)
The CM_Get_Res_Des_Data_Size function obtains the buffer size required to hold the information contained in a specified resource descriptor on the local machine.
Syntax
CMAPI CONFIGRET CM_Get_Res_Des_Data_Size(
[out] PULONG pulSize,
[in] RES_DES rdResDes,
[in] ULONG ulFlags
);
Parameters
[out] pulSize
Caller-supplied address of a location to receive the required buffer size.
[in] rdResDes
Caller-supplied handle to a resource descriptor, obtained by a previous call to CM_Get_Next_Res_Des.
[in] ulFlags
Not used, must be zero.
Return value
If the operation succeeds, the function returns CR_SUCCESS. Otherwise, it returns one of the CR_-prefixed error codes defined in Cfgmgr32.h.
Remarks
The returned size value represents the size of the appropriate resource structure (see CM_Add_Res_Des). If the resource descriptor resides in a resource requirements list, the returned size includes both the size of the resource structure and the space allocated for associated range arrays.
