SYSCALL_MODULE(9)

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
The SYSCALL_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.
