Remove hardcoded numbers from snprintf() call in every test program.
Also, remove those redundant backslashes in typically long snprintf statements
switch(poll(fds, 1, (int)(end - time(NULL)))) // Line 118: tests/mkdir-atf0.cAssuming the type casting is right, the poll(2) system call should return a possible timeout in case mkdir(2) can not be audited. However, it returns "invalid argument" as shown by errno.
