The man page for fts library call states both the following:
short fts_pathlen; /* strlen(fts_path) */
fts_pathlen The length of the string referenced by fts_path
However, for the structures returned from fts_children() function,
fts_pathlen is strlen(fts_path) + strlen(fts_name), which contradicts
the man page statement. So I believe that there is either a bug in the
man page or the fts_children() library call.
The following program can be used for verification:
#include <fts.h>
#include <pwd.h>
#include <stdio.h>
#include <string.h>
int main() {
struct passwd *pwd_entry = getpwuid(getuid());
char *paths[] = {pwd_entry->pw_dir, NULL};
FTS* fts = fts_open(paths, FTS_LOGICAL, NULL);
FTSENT* ftsent = fts_read(fts);
FTSENT* child = fts_children(fts, 0);
while (child != NULL) {
printf("\n %s %s %d %lu", child->fts_path, child->fts_name,
child->fts_pathlen, strlen(child->fts_path));
child = child->fts_link;
}
return 0;
}
