+.SH DESCRIPTION
+.PP
+These procedures provide a platform and compiler independent interface
+for memory allocation.  Programs that need to transfer ownership of
+memory blocks between Tcl and other modules should use these routines
+rather than the native \fBmalloc()\fR and \fBfree()\fR routines
+provided by the C run-time library.
+.PP
+\fBTcl_Alloc\fR returns a pointer to a block of at least \fIsize\fR
+bytes suitably aligned for any use.
+.PP
+\fBTcl_Free\fR makes the space referred to by \fIptr\fR available for
+further allocation.
+.PP
+\fBTcl_Realloc\fR changes the size of the block pointed to by
+\fIptr\fR to \fIsize\fR bytes and returns a pointer to the new block.
+The contents will be unchanged up to the lesser of the new and old
+sizes.  The returned location may be different from \fIptr\fR.

+
+.SH DESCRIPTION
+.PP
+These procedures may be used to disassemble and reassemble file
+paths in a platform independent manner: they provide C-level access to
+the same functionality as the \fBfile split\fR, \fBfile join\fR, and
+\fBfile pathtype\fR commands.
+.PP
+\fBTcl_SplitPath\fR breaks a path into its constituent elements,
+returning an array of pointers to the elements using \fIargcPtr\fR and
+\fIargvPtr\fR.  The area of memory pointed to by \fI*argvPtr\fR is
+dynamically allocated; in addition to the array of pointers, it also
+holds copies of all the path elements.  It is the caller's
+responsibility to free all of this storage.
+For example, suppose that you have called \fBTcl_SplitPath\fR with the
+following code:
+.CS
+int argc, code;
+char *path;
+char **argv;
+\&...
+code = Tcl_SplitPath(interp, string, &argc, &argv);
+.CE
+Then you should eventually free the storage with a call like the
+following:
+.CS
+Tcl_Free((char *) argv);
+.CE
+.PP
+\fBTcl_JoinPath\fR is the inverse of \fBTcl_SplitPath\fR: it takes a
+collection of path elements given by \fIargc\fR and \fIargv\fR and
+generates a result string that is a properly constructed path. The
+result string is appended to \fIresultPtr\fR.  \fIResultPtr\fR must
+refer to an initialized \fBTcl_DString\fR.
+.PP
+If the result of \fBTcl_SplitPath\fR is passed to \fBTcl_JoinPath\fR,
+the result will refer to the same location, but may not be in the same
+form.  This is because \fBTcl_SplitPath\fR and \fBTcl_JoinPath\fR
+eliminate duplicate path separators and return a normalized form for
+each platform.
+.PP
+\fBTcl_GetPathType\fR returns the type of the specified \fIpath\fR,
+where \fBTcl_PathType\fR is one of \fBTCL_PATH_ABSOLUTE\fR,
+\fBTCL_PATH_RELATIVE\fR, or \fBTCL_PATH_VOLUME_RELATIVE\fR.  See the
+\fBfilename\fR manual entry for a description of the path types for
+each platform.
