+\fBTcl_Realloc\fR(\fIptr, size\fR)

+Size in bytes of the memory block to allocate.
+.AP char *ptr in
+Pointer to memory block to free or realloc.

+.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.
