NAME

       user_regset_set_fn - type of set function in struct user_regset

SYNOPSIS

       typedef int user_regset_set_fn(struct task_struct * target, const struct user_regset * regset, unsigned int pos, unsigned int count,
				      const void * kbuf, const void __user * ubuf);

ARGUMENTS

       target
	   thread being examined

       regset
	   regset being examined

       pos
	   offset into the regset data to access, in bytes

       count
	   amount of data to copy, in bytes

       kbuf
	   if not NULL, a kernel-space pointer to copy from

       ubuf
	   if kbuf is NULL, a user-space pointer to copy from

DESCRIPTION

       Store register values. Return 0 on success; -EIO or -ENODEV are usual failure returns. The pos and count values are in bytes, but must be
       properly aligned. If kbuf is non-null, that buffer is used and ubuf is ignored. If kbuf is NULL, then ubuf gives a userland pointer to
       access directly, and an -EFAULT return value is possible.

NAME

       explain_ustat_or_die - get file system statistics and report errors

SYNOPSIS

       #include <libexplain/ustat.h>
       void explain_ustat_or_die(dev_t dev, struct ustat *ubuf);
       int explain_ustat_on_error(dev_t dev, struct ustat *ubuf);

DESCRIPTION

       The  explain_ustat_or_die  function is used to call the ustat(2) system call. On failure an explanation will be printed to stderr, obtained
       from the explain_ustat(3) function, and then the process terminates by calling exit(EXIT_FAILURE).

       The explain_ustat_on_error function is used to call the ustat(2) system call. On failure an explanation will be printed to stderr, obtained
       from the explain_ustat(3) function, but still returns to the caller.

       dev     The dev, exactly as to be passed to the ustat(2) system call.

       ubuf    The ubuf, exactly as to be passed to the ustat(2) system call.

RETURN VALUE

       The  explain_ustat_or_die function only returns on success, see ustat(2) for more information. On failure, prints an explanation and exits,
       it does not return.

       The explain_ustat_on_error function always returns the value return by the wrapped ustat(2) system call.

EXAMPLE

       The explain_ustat_or_die function is intended to be used in a fashion similar to the following example:
	      explain_ustat_or_die(dev, ubuf);

SEE ALSO

       ustat(2)
	       get file system statistics

       explain_ustat(3)
	       explain ustat(2) errors

       exit(2) terminate the calling process
