Dynamic arrays in C?

Are there any libraries that can help me realloc and free pointers automatically? I have hand-coded a varstring.c to help me with unknown string lengths. But are there alternatives by other people, not for just char but also pointers?

I don't know if this is of any help, but from what I understand ISO C99 has variable length arrays (VLA's) and GNU C dynamic arrays. Being primarily a C++ programmer myself I have no experience with these.

You could use "map" perhaps?

glib does stuff like that. You probably already have it installed, as it's a prerequisite for gtk. If you don't,

To expand a bit on the previous answer. I use GArray and GPtrArray (see API documentation) available in GLib. You can append, insert and remove elements. You can also sort and search such arrays. I find them very useful and convenient to use.

You could always consider using C++. There's all kinds of fun stuff in the STL for things like this, and it's all template-based so you can use it with whatever type you want.
