int path_simplify (  char *  path  )

simplifies path - removes /./ or // returns 0 if OK else -1 and fills errno

char** path_split (  char *  path, char  sep )

splits a path in pieces e.g: "//foo//bar" becomes {"", "", "foo", "", "bar", NULL} returns NULL if a memory problem was encountered

char* path_treat (  char *  path, u_int32_t  opts, char *  wd, t_path_gate_fn  path_gate, int *  gate_returned, char *  s )

treat a path before any operations on it - should be called before any path lookup: (see options). If OK returns newly allocated pointer, else returns NULL and errno filled. Parameters: path  input path opts  options wd  work directory path_gate  or NULL (should set errno) s  comment for debug

int userland_path_gate (  char *  npath, int *  gate_returned )
