task_get_emulation_vector

Function - Return an array identifying the target task's user-level system call handlers.

SYNOPSIS

kern_return_t   task_get_emulation_vector
                (task_t                                    task,
                 int                               vector_start,
                 emulation_vector_t            emulation_vector,
                 mach_msg_type_number_t* emulation_vector_count);

PARAMETERS

task

[in task send right] The port for the task for which the system call handler addresses are desired.

vector_start

[out scalar] The syscall number corresponding to the first element of emulation_vector.

emulation_vector

[out pointer to dynamic array of vm_address_t] Pointer to the returned array of routine entrypoints for the system calls starting with syscall number vector_start.

emulation_vector_count

[out scalar] The number of entries filled by the kernel.

DESCRIPTION

The task_get_emulation_vector function returns the user-level syscall handler entrypoint addresses.

NOTES

This interface is machine word length specific because of the virtual addresses in the emulation_vector parameter.

RETURN VALUES

Only generic errors apply.
