6.6.5 COUNT (Number of Elements in an Array)

Description:

When ARY is used, it must be followed by a definition of COUNT, which indicates the number of

elements in the array to be passed between the client and the server.

(1) When the input/output keyword selected for ARY is IN

In this case, a parameter specification that includes ARY must be followed by a single definition

of COUNT to indicate the number of elements in the array.

COUNT is an expression that specifies the number of elements in the array to be passed from the

client to the server.

RPCGEN creates client-stub code that makes an RPC call after setting the size of an input IOVEC

structure by using an expression of the kind specified in figure 6.2. This must be taken into

account when COUNT is defined. For example, the expression for COUNT must not contain any

variables that hold the return value of a function. Figures 6.2 and 6.3 show the code for example 5

(without SVR_AUTH) of the examples introduced following the figures.

int func (struct INF * inf, struct ST * ptr )

{

IOVEC __input[2];

...

__input[ __ulInputParamCount ].pBaseAddress = (UINT8 *)(inf);

__input[ __ulInputParamCount++ ].ulSize = sizeof(*inf);

...

if (((UINT32)(inf->count)) > 0UL)

{

__input[ __ulInputParamCount ].pBaseAddress = (UINT8 *)(ptr);

__input[ __ulInputParamCount++ ].ulSize = sizeof(*ptr) * ((UINT32)(inf->count));

}

...

rpc_call(...);

}
