25There is still some work to be done:
26
27- unknown behaviour if files>=2GB or cabinet >=4GB
28- check if the maximum size for a cabinet is too small to store any data
29- call pfnfcignc on exactly the same position as MS FCIAddFile in every case

954 * FCICreate (CABINET.10)
955 *
956 * FCICreate is provided with several callbacks and
957 * returns a handle which can be used to create cabinet files.
958 *
959 * PARAMS
960 * perf [IO] A pointer to an ERF structure. When FCICreate
961 * returns an error condition, error information may
962 * be found here as well as from GetLastError.
963 * pfnfiledest [I] A pointer to a function which is called when a file
964 * is placed. Only useful for subsequent cabinet files.
965 * pfnalloc [I] A pointer to a function which allocates ram. Uses
966 * the same interface as malloc.
967 * pfnfree [I] A pointer to a function which frees ram. Uses the
968 * same interface as free.
969 * pfnopen [I] A pointer to a function which opens a file. Uses
970 * the same interface as _open.
971 * pfnread [I] A pointer to a function which reads from a file into
972 * a caller-provided buffer. Uses the same interface
973 * as _read.
974 * pfnwrite [I] A pointer to a function which writes to a file from
975 * a caller-provided buffer. Uses the same interface
976 * as _write.
977 * pfnclose [I] A pointer to a function which closes a file handle.
978 * Uses the same interface as _close.
979 * pfnseek [I] A pointer to a function which seeks in a file.
980 * Uses the same interface as _lseek.
981 * pfndelete [I] A pointer to a function which deletes a file.
982 * pfnfcigtf [I] A pointer to a function which gets the name of a
983 * temporary file.
984 * pccab [I] A pointer to an initialized CCAB structure.
985 * pv [I] A pointer to an application-defined notification
986 * function which will be passed to other FCI functions
987 * as a parameter.
988 *
989 * RETURNS
990 * On success, returns an FCI handle of type HFCI.
991 * On failure, the NULL file handle is returned. Error
992 * info can be retrieved from perf.
