问题 I'm trying to get all .c files in a directory tree using nftw with the following code: static int gf(const char *path, const struct stat *st, int t, struct FTW *ftw) { if (t != FTW_F) return 0; if (strcmp(ext(path), ".c") == 0) addl(&files, dup(abspath(path))); return 0; } void getfiles(char *path) { nftw(path, gf, 255, FTW_PHYS); } It works on Linux and Solaris, but on PC-BSD it fails by simply not picking up any files. What am I missing? 回答1: What is the return value of nftw ? If it's -1

How avoid using global variable when using nftw

I want to use nftw to traverse a directory structure in C. However, given what I want to do, I don't see a way around using a global variable. The textbook examples of using (n)ftw all involve doing something like printing out a filename. I want, instead, to take the pathname and file checksum and place those in a data structure. But I don't see a good way to do that, given the limits on what can be passed to nftw. The solution I'm using involves a global variable. The function called by nftw can then access that variable and add the required data. Is there any reasonable way to do this
