Error checks missing in my code or elsewhere? Also, what should I do on
an unlink failure? I thought of printing a message but wasn't sure:
if ((db_dir = opendir(db_path)) != NULL)
while ((db_de = readdir(db_dir)) != NULL)
{
snprintf(temp_path, sizeof(temp_path),
"%s/%s/%s/", db_path, db_de->d_name, SORT_TEMP_DIR);
if ((temp_dir = opendir(temp_path)) != NULL)
while ((temp_de = readdir(temp_dir)) != NULL)
{
if (strspn(temp_de->d_name, "0123456789.") ==
strlen(temp_de->d_name))
{
snprintf(rm_path, sizeof(temp_path),
"%s/%s/%s/%s",
db_path, db_de->d_name,
SORT_TEMP_DIR, temp_de->d_name);
unlink(rm_path);
}
}
}
