+ +Function silc_srealloc

+ + +SYNOPSIS + +

+    void *silc_srealloc(SilcStack stack, SilcUInt32 old_size,
+                        void *ptr, SilcUInt32 size);
+
+
+DESCRIPTION + +

+    Change the size of the memory block indicated by `ptr' to the new
+    size of `size' bytes.  The contents of `ptr' will not be changed.
+    If `ptr' is NULL the call is equivalent to silc_smalloc.  If `size'
+    is zero (0) error will occur.  Returns NULL on error and the old
+    pointer remain intact.
+
+
+NOTES + +

+    This function reallocates successfully only if the previous allocation
+    to `stack' was `ptr'.  If there was another memory allocation between
+    allocating `ptr' and this call, this routine will return NULL.  The
+    NULL is also returned if the `size' does not fit to current stack
+    and allocating new block would require slow copying of the data.  It
+    is left to the caller to decide whether to allocate new pointer and
+    copy the old data in case this function returns NULL.
+
+    This function can be used to reallocate only aligned memory allocated
+    with silc_smalloc.
+
+    If `stack' is NULL this function calls silc_realloc.
