preadv on score
read or write data into multiple buffers
sys_preadv(unsigned long fd, const struct iovec *vec, unsigned long vlen, unsigned long pos_l, unsigned long pos_h)| number | 69 (0x45) |
|---|---|
| abi | common |
| entry point | sys_preadv |
| since | Linux 3.7 or earlier (3.7 is the first release scanned for score) |
| man page | preadv(2) |
| source | elixir.bootlin.com |
Registers
| register | value |
|---|---|
r27 | 69, the syscall number |
r4 | unsigned long fd |
r5 | const struct iovec *vec |
r6 | unsigned long vlen |
r7 | unsigned long pos_l |
r8 | unsigned long pos_h |
r4 | the return value |
Then run syscall to enter the kernel.
r7 is the error flag and r4 then holds the positive error number.
This architecture was removed from the Linux kernel in Linux 4.17. The newest release with a syscall table here is Linux 4.16. The other removed architectures live on the historical architectures page.
