9 '\" The definitions below are for supplemental macros used in Tcl/Tk
12 '\" .AP type name in/out ?indent?
13 '\" Start paragraph describing an argument to a library procedure.
14 '\" type is type of argument (int, etc.), in/out is either "in", "out",
15 '\" or "in/out" to describe whether procedure reads or modifies arg,
16 '\" and indent is equivalent to second arg of .IP (shouldn't ever be
17 '\" needed; use .AS below instead)
20 '\" Give maximum sizes of arguments for setting tab stops. Type and
21 '\" name are examples of largest possible arguments that will be passed
22 '\" to .AP later. If args are omitted, default tab stops are used.
25 '\" Start box enclosure. From here until next .BE, everything will be
26 '\" enclosed in one large box.
29 '\" End of box enclosure.
32 '\" Begin code excerpt.
37 '\" .VS ?version? ?br?
38 '\" Begin vertical sidebar, for use in marking newly-changed parts
39 '\" of man pages. The first argument is ignored and used for recording
40 '\" the version when the .VS was added, so that the sidebars can be
41 '\" found and removed when they reach a certain age. If another argument
42 '\" is present, then a line break is forced before starting the sidebar.
45 '\" End of vertical sidebar.
48 '\" Begin an indented unfilled display.
51 '\" End of indented unfilled display.
54 '\" Start of list of standard options for a Tk widget. The
55 '\" options follow on successive lines, in four columns separated
59 '\" End of list of standard options for a Tk widget.
61 '\" .OP cmdName dbName dbClass
62 '\" Start of description of a specific option. cmdName gives the
63 '\" option's name as specified in the class command, dbName gives
64 '\" the option's name in the option database, and dbClass gives
65 '\" the option's class in the option database.
68 '\" Print arg1 underlined, then print arg2 normally.

245 .TH Tcl_SplitPath 3 7.5 Tcl "Tcl Library Procedures"
248 Tcl_SplitPath, Tcl_JoinPath, Tcl_GetPathType \- manipulate platform-dependent file paths
251 \fB#include <tcl.h>\fR
253 \fBTcl_SplitPath\fR(\fIpath, argcPtr, argvPtr\fR)
256 \fBTcl_JoinPath\fR(\fIargc, argv, resultPtr\fR)
259 \fBTcl_GetPathType\fR(\fIpath\fR)
261 .AS Tcl_DString ***argvPtr
263 File path in a form appropriate for the current platform (see the
264 \fBfilename\fR manual entry for acceptable forms for path names).
266 Filled in with number of path elements in \fIpath\fR.
267 .AP char ***argvPtr out
268 \fI*argvPtr\fR will be filled in with the address of an array of
269 pointers to the strings that are the extracted elements of \fIpath\fR.
270 There will be \fI*argcPtr\fR valid entries in the array, followed by
273 Number of elements in \fIargv\fR.
275 Array of path elements to merge together into a single path.
276 .AP Tcl_DString *resultPtr in/out
277 A pointer to an initialized \fBTcl_DString\fR to which the result of
278 \fBTcl_JoinPath\fR will be appended.
283 These procedures may be used to disassemble and reassemble file
284 paths in a platform independent manner: they provide C-level access to
285 the same functionality as the \fBfile split\fR, \fBfile join\fR, and
286 \fBfile pathtype\fR commands.
288 \fBTcl_SplitPath\fR breaks a path into its constituent elements,
289 returning an array of pointers to the elements using \fIargcPtr\fR and
290 \fIargvPtr\fR. The area of memory pointed to by \fI*argvPtr\fR is
291 dynamically allocated; in addition to the array of pointers, it also
292 holds copies of all the path elements. It is the caller's
293 responsibility to free all of this storage.
294 For example, suppose that you have called \fBTcl_SplitPath\fR with the
301 Tcl_SplitPath(string, &argc, &argv);
303 Then you should eventually free the storage with a call like the
306 Tcl_Free((char *) argv);
309 \fBTcl_JoinPath\fR is the inverse of \fBTcl_SplitPath\fR: it takes a
310 collection of path elements given by \fIargc\fR and \fIargv\fR and
311 generates a result string that is a properly constructed path. The
312 result string is appended to \fIresultPtr\fR. \fIResultPtr\fR must
313 refer to an initialized \fBTcl_DString\fR.
315 If the result of \fBTcl_SplitPath\fR is passed to \fBTcl_JoinPath\fR,
316 the result will refer to the same location, but may not be in the same
317 form. This is because \fBTcl_SplitPath\fR and \fBTcl_JoinPath\fR
318 eliminate duplicate path separators and return a normalized form for
321 \fBTcl_GetPathType\fR returns the type of the specified \fIpath\fR,
322 where \fBTcl_PathType\fR is one of \fBTCL_PATH_ABSOLUTE\fR,
323 \fBTCL_PATH_RELATIVE\fR, or \fBTCL_PATH_VOLUME_RELATIVE\fR. See the
324 \fBfilename\fR manual entry for a description of the path types for
