24 There is still some work to be done:
26 - no real compression yet
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

113 * FCICreate (CABINET.10)
115 * FCICreate is provided with several callbacks and
116 * returns a handle which can be used to create cabinet files.
119 * perf [IO] A pointer to an ERF structure. When FCICreate
120 * returns an error condition, error information may
121 * be found here as well as from GetLastError.
122 * pfnfiledest [I] A pointer to a function which is called when a file
123 * is placed. Only useful for subsequent cabinet files.
124 * pfnalloc [I] A pointer to a function which allocates ram. Uses
125 * the same interface as malloc.
126 * pfnfree [I] A pointer to a function which frees ram. Uses the
127 * same interface as free.
128 * pfnopen [I] A pointer to a function which opens a file. Uses
129 * the same interface as _open.
130 * pfnread [I] A pointer to a function which reads from a file into
131 * a caller-provided buffer. Uses the same interface
133 * pfnwrite [I] A pointer to a function which writes to a file from
134 * a caller-provided buffer. Uses the same interface
136 * pfnclose [I] A pointer to a function which closes a file handle.
137 * Uses the same interface as _close.
138 * pfnseek [I] A pointer to a function which seeks in a file.
139 * Uses the same interface as _lseek.
140 * pfndelete [I] A pointer to a function which deletes a file.
141 * pfnfcigtf [I] A pointer to a function which gets the name of a
143 * pccab [I] A pointer to an initialized CCAB structure.
144 * pv [I] A pointer to an application-defined notification
145 * function which will be passed to other FCI functions
149 * On success, returns an FCI handle of type HFCI.
150 * On failure, the NULL file handle is returned. Error
151 * info can be retrieved from perf.
