NAME

       suibyte - General: Writes a byte into user instruction address space

NOTES

       The  suibyte  routine  is  for use on machines that have separate address spaces for code and data. Because the Alpha architecture does not
       have separate address spaces for code and data, suibyte is mapped to subyte.  The suibyte routine is provided  for  compatibility  reasons.
       See the routine description for subyte for a complete description of suibyte.

NAME

     store, subyte, suibyte, suiword, sulong, suulong, suword -- store data to user-space

SYNOPSIS

     #include <sys/types.h>
     #include <sys/time.h>
     #include <sys/systm.h>
     #include <sys/resourcevar.h>

     int
     subyte(user_addr_t addr, int byte);

     int
     suibyte(user_addr_t addr, int byte);

     int
     suiword(user_addr_t addr, int word);

     int
     sulong(user_addr_t addr, int64_t longword);

     int
     suulong(user_addr_t addr, uint64_t longword);

     int
     suword(user_addr_t addr, int word);

DESCRIPTION

     The store functions are designed to copy small amounts of data to user-space.

     The store routines provide the following functionality:

     subyte()	Stores a byte of data to the user-space address addr.

     suibyte()	Stores a byte of data to the user-space address addr.  This function is safe to call during an interrupt context.

     suiword()	Stores a word of data to the user-space address addr.  This function is safe to call during an interrupt context.

     sulong()	Stores a long word of data to the user-space address addr.

     suulong()	Stores a unsigned long word of data to the user-space address addr.

     suword()	Stores a word of data to the user-space address addr.

RETURN VALUES

     The store functions return 0 on success or -1 on failure.
