NAME
SYSCALL_MODULE —
syscall kernel module declaration
macro
SYNOPSIS
#include
<sys/proc.h>
#include <sys/module.h>
#include <sys/sysent.h>
SYSCALL_MODULE(name,
int *offset,
struct sysent new_sysent,
modeventhand_t evh,
void *arg);
DESCRIPTION
TheSYSCALL_MODULE()
macro declares a new syscall. SYSCALL_MODULE() expands
into a kernel module declaration named as name.
offset is a pointer to an int which saves the offset in struct sysent where the syscall is allocated.
new_sysent specifies the function
implementing the syscall and the number of arguments this function needs
(see <sys/sysent.h>).
evh is a pointer to the kernel module event handler function with the argument arg. Please refer to module(9) for more information.
EXAMPLES
A minimal example for a syscall module can be found in /usr/share/examples/kld/syscall/module/syscall.c.
