| 14 | This file exposes the system call number and argument registers for the | |
| 15 | system call currently being executed by the process, | |
| 16 | followed by the values of the stack pointer and program counter registers. | |
| 17 | The values of all six argument registers are exposed, | |
| 18 | although most system calls use fewer registers. | |
| 19 | .IP | |
| 20 | If the process is blocked, but not in a system call, | |
| 21 | then the file displays \-1 in place of the system call number, | |
| 22 | followed by just the values of the stack pointer and program counter. | |
| 23 | If process is not blocked, then the file contains just the string "running". | |
