TASK_USER_REGSET_VIE(9) 					   Machine State					   TASK_USER_REGSET_VIE(9)

NAME

       task_user_regset_view - Return the process's native regset view.

SYNOPSIS

       const struct user_regset_view * task_user_regset_view(struct task_struct * tsk);

ARGUMENTS

       tsk
	   a thread of the process in question

DESCRIPTION

       Return the struct user_regset_view that is native for the given process. For example, what it would access when it called ptrace.
       Throughout the life of the process, this only changes at exec.

NAME

       call_usermodehelper_setup - prepare to call a usermode helper

SYNOPSIS

       struct subprocess_info * call_usermodehelper_setup(char * path, char ** argv, char ** envp, gfp_t gfp_mask,
							  int (*init) (struct subprocess_info *info, struct cred *new),
							  void (*cleanup) (struct subprocess_info *info), void * data);

ARGUMENTS

       path
	   path to usermode executable

       argv
	   arg vector for process

       envp
	   environment for process

       gfp_mask
	   gfp mask for memory allocation

       init
	   an init function

       cleanup
	   a cleanup function

       data
	   arbitrary context sensitive data

DESCRIPTION

       Returns either NULL on allocation failure, or a subprocess_info structure. This should be passed to call_usermodehelper_exec to exec the
       process and free the structure.

       The init function is used to customize the helper process prior to exec. A non-zero return code causes the process to error out, exit, and
       return the failure to the calling process

       The cleanup function is just before ethe subprocess_info is about to be freed. This can be used for freeing the argv and envp. The Function
       must be runnable in either a process context or the context in which call_usermodehelper_exec is called.
