Parameters

[in, out] perf

Pointer to an ERF structure that receives the error information.

[in] pfnfcifp

Pointer to an application-defined callback function to notify when a file is placed in the cabinet. The function should be declared using the FNFCIFILEPLACED macro.

[in] pfna

Pointer to an application-defined callback function to allocate memory. The function should be declared using the FNFCIALLOC macro.

[in] pfnf

Pointer to an application-defined callback function to free previously allocated memory. The function should be declared using the FNFCIFREE macro.

[in] pfnopen

Pointer to an application-defined callback function to open a file. The function should be declared using the FNFCIOPEN macro.

[in] pfnread

Pointer to an application-defined callback function to read data from a file. The function should be declared using the FNFCIREAD macro.

[in] pfnwrite

Pointer to an application-defined callback function to write data to a file. The function should be declared using the FNFCIWRITE macro.

[in] pfnclose

Pointer to an application-defined callback function to close a file. The function should be declared using the FNFCICLOSE macro.

[in] pfnseek

Pointer to an application-defined callback function to move a file pointer to the specific ___location. The function should be declared using the FNFCISEEK macro.

[in] pfndelete

Pointer to an application-defined callback function to delete a file. The function should be declared using the FNFCIDELETE macro.

[in] pfnfcigtf

Pointer to an application-defined callback function to retrieve a temporary file name. The function should be declared using the FNFCIGETTEMPFILE macro.

[in] pccab

Pointer to a CCAB structure that contains the parameters for creating a cabinet.

[in, optional] pv

Pointer to an application-defined value that is passed to callback functions.

Return value

If the function succeeds, it returns a non-NULL HFCI context pointer; otherwise, NULL.

Extended error information is provided in the ERF structure.

Remarks

FCI supports multiple simultaneous contexts. As a result it is possible to create or extract multiple cabinets at the same time within the same application. If the application is multithreaded, it is also possible to run a different context in each thread; however, an application cannot use the same context simultaneously in multiple threads. For example, FCIAddFile cannot be called from two different threads, using the same FCI context.
