24 There is still some work to be done:
25
26 - the ERF error structure aren't used on error
27 - no real compression yet
28 - unknown behaviour if files>4GB or cabinet >4GB
29 - incorrect status information
30 - check if the maximum size for a cabinet is too small to store any data
31 - call pfnfcignc on exactly the same position as MS FCIAddFile in every case

110 * FCICreate (CABINET.10)
111 *
112 * FCICreate is provided with several callbacks and
113 * returns a handle which can be used to create cabinet files.
114 *
115 * PARAMS
116 * perf [IO] A pointer to an ERF structure. When FCICreate
117 * returns an error condition, error information may
118 * be found here as well as from GetLastError.
119 * pfnfiledest [I] A pointer to a function which is called when a file
120 * is placed. Only useful for subsequent cabinet files.
121 * pfnalloc [I] A pointer to a function which allocates ram. Uses
122 * the same interface as malloc.
123 * pfnfree [I] A pointer to a function which frees ram. Uses the
124 * same interface as free.
125 * pfnopen [I] A pointer to a function which opens a file. Uses
126 * the same interface as _open.
127 * pfnread [I] A pointer to a function which reads from a file into
128 * a caller-provided buffer. Uses the same interface
129 * as _read.
130 * pfnwrite [I] A pointer to a function which writes to a file from
131 * a caller-provided buffer. Uses the same interface
132 * as _write.
133 * pfnclose [I] A pointer to a function which closes a file handle.
134 * Uses the same interface as _close.
135 * pfnseek [I] A pointer to a function which seeks in a file.
136 * Uses the same interface as _lseek.
137 * pfndelete [I] A pointer to a function which deletes a file.
138 * pfnfcigtf [I] A pointer to a function which gets the name of a
139 * temporary file.
140 * pccab [I] A pointer to an initialized CCAB structure.
141 * pv [I] A pointer to an application-defined notification
142 * function which will be passed to other FCI functions
143 * as a parameter.
144 *
145 * RETURNS
146 * On success, returns an FCI handle of type HFCI.
147 * On failure, the NULL file handle is returned. Error
148 * info can be retrieved from perf.
149 *
150 * INCLUDES
151 * fci.h
