2 | * I'm tired of doing "vsnprintf()" etc just to open a | |
3 | * file, so here's a "return static buffer with printf" | |
4 | * interface for paths. | |
5 | * | |
6 | * It's obviously not thread-safe. Sue me. But it's quite | |
7 | * useful for doing things like | |
8 | * | |
9 | * f = open(mkpath("%s/%s.git", base, name), O_RDONLY); | |
10 | * | |
11 | * which is what it's designed for. | |
