NAMEuser_regset_writeback_fn − type of writeback function in struct user_regset
SYNOPSIStypedef int user_regset_writeback_fn(struct task_struct * target, const struct user_regset * regset, int immediate);
ARGUMENTStarget thread being examined regset regset being examined immediate zero if writeback at completion of next context switch is OK
DESCRIPTIONThis call is optional; usually the pointer is NULL​. When provided, there is some user memory associated with this regset´s hardware, such as memory backing cached register data on register window machines; the regset´s data controls what user memory is used (e​.g​. via the stack pointer value)​. Write register data back to user memory​. If the immediate flag is nonzero, it must be written to the user memory so uaccess or access_process_vm can see it when this call returns; if zero, then it must be written back by the time the task completes a context switch (as synchronized with wait_task_inactive)​. Return 0 on success or if there was nothing to do, −EFAULT for a memory problem (bad stack pointer or whatever), or −EIO for a hardware problem​. 0
