+The remaining arguments should be the same arguments that were passed
+to the primitive. Depending on which primitive, one of those arguments
+is selected as the TARGET. For example, if OPERATION does file I/O,
+whichever argument specifies the file name is TARGET.
+
+TARGET has a meaning which depends on OPERATION:
+ For file I/O, TARGET is a file name (except for the special case below).
+ For process I/O, TARGET is a process name.
+ For network I/O, TARGET is a service name or a port number
+
+This function looks up what specified for TARGET in,
+`file-coding-system-alist', `process-coding-system-alist',
+or `network-coding-system-alist' depending on OPERATION.
+They may specify a coding system, a cons of coding systems,
+or a function symbol to call.
+In the last case, we call the function with one argument,
+which is a list of all the arguments given to this function.
+If the function can't decide a coding system, it can return
+`undecided' so that the normal code-detection is performed.
+
+If OPERATION is `insert-file-contents', the argument corresponding to
+TARGET may be a cons (FILENAME . BUFFER). In that case, FILENAME is a
+file name to look up, and BUFFER is a buffer that contains the file's
+contents (not yet decoded). If `file-coding-system-alist' specifies a
+function to call for FILENAME, that function should examine the
+contents of BUFFER instead of reading the file.
