STORE(9)						   BSD Kernel Developer's Manual						  STORE(9)

NAME

     store, subyte, suswintr, suword -- store data to user-space

SYNOPSIS

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

     int
     subyte(volatile void *base, int byte);

     int
     suword(volatile void *base, long word);

     int
     suword16(volatile void *base, int word);

     int
     suword32(volatile void *base, int32_t word);

     int
     suword64(volatile void *base, int64_t word);

     #include <sys/resourcevar.h>

     int
     suswintr(void *base, int word);

DESCRIPTION

     The store functions are designed to copy small amounts of data to user-space.  If write is successful, it is performed atomically.  The data
     written must be naturally aligned.

     The store routines provide the following functionality:

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

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

     suword16()  Stores 16 bits of data to the user-space address base.

     suword32()  Stores 32 bits of data to the user-space address base.

     suword64()  Stores 64 bits of data to the user-space address base.

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

RETURN VALUES

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