NAME

- long syscall_get_return_value(struct task_struct * task, struct pt_regs * regs);
ARGUMENTS

DESCRIPTION
Returns the return value of the successful system call. This value is meaningless if syscall_get_error returned nonzero.
It's only valid to call this when task is stopped for tracing on exit from a system call, due to TIF_SYSCALL_TRACE or TIF_SYSCALL_AUDIT.
