NAME¶
store, subyte, suswintr, suword — store data to user-spaceSYNOPSIS¶
#include <sys/types.h>#include <sys/time.h>
#include <sys/systm.h> int
subyte(void *base, int byte); int
suword(void *base, long word); int
suword16(void *base, int word); int
suword32(void *base, int32_t word); int
suword64(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. 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 of data to the user-space address base.
- suword32()
- Stores 32 bits of of data to the user-space address base.
- suword64()
- Stores 64 bits of 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.SEE ALSO¶
