PISSYSCALL(3PROC) Process Control Library Functions PISSYSCALL(3PROC)

Pissyscall, Pissyscall_prev
determine if instructions are system call instructions

Process Control Library (libproc, -lproc)

#include <libproc.h>

int
Pissyscall(struct ps_prochandle *P, uintptr_t addr);

int
Pissyscall_prev(struct ps_prochandle *P, uintptr_t addr, uintptr_t *dst);

The Pissyscall() function determines whether or not the instructions at addr in the process handle P corresponds to one of the architecture's system call instructions.

the Pissyscall_prev() function determines whether or not the instruction before addr in the process handle P corresponds to one of the architecture's system call instructions. If it does, and dst is a non-NULL pointer, then the address of the system call instruction will be copied into the location pointed to by dst.

Upon successful completion, the Pissyscall() function returns non-zero if addr corresponds to a system call instruction. Otherwise, 0 is returned.

Upon successful completion, the Pissyscall_prev() function returns non-zero if addr corresponds to a system call instruction and if dst is non-NULL, dst is updated. Otherwise, 0 is returned.
