getppid
Implemented in Antinomie 0.7.0 · Syscall list
Synopsis
Section titled “Synopsis”long getppid(void);| Number (x86-64) | 110 |
| ABI | common |
| Kernel entry point | sys_getppid |
This is the raw kernel prototype from the pinned Linux 6.12.94 schema, not the libc wrapper.
Description
Section titled “Description”Returns the process id of the caller’s parent.
Arguments
Section titled “Arguments”The call takes no arguments.
Return value
Section titled “Return value”On success: the parent process id.
In an Antinomie trace the Return column and the ret filter field show the raw kernel return value. On failure that is the negative errno, for example -2 for ENOENT, not the -1 plus errno that the libc wrapper gives. syscall.errno holds the positive errno and syscall.success is false.
Man page
Section titled “Man page”Captured by Antinomie
Section titled “Captured by Antinomie”Coverage mark: Implemented. All arguments are plain values, recorded as the raw argument words at entry. There is no pointee to copy and no known gap.
Every call is recorded as an Entry record (the six argument words and the pointees copied at entry) and an Exit record (the return value and the pointees copied at exit).
