sys_wait4(pid_t pid, int *stat_addr, int options, struct rusage *ru)| number | 260 (0x104) |

| abi | common |
| entry point | sys_wait4 |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |

Registers
| register | value |
|---|---|
r27 | 260, the syscall number |
r4 | pid_t pid |
r5 | int *stat_addr |
r6 | int options |
r7 | struct rusage *ru |
r4 | the return value |
