For general inspiration: We have an in-house to/from string library, where our xx_to_str() functions return char * and can take a NULL pointer as the buffer parameter to make it use a buffer from an small cyclic pool of string buffers in the library. Probably not good from an academic standpoint, and not good for a generic library, but we know how many of these strings are being used simultaneously in our applications, so the pool is not overrun in reality. And it makes the code using these functions much shorter and readable. -Morten
