#include <sys/types.h> #include <sys/time.h> #include <sys/systm.h> int fubyte(const void *base); long fuword(const void *base); int fuword16(void *base); int32_t fuword32(const void *base); int64_t fuword64(const void *base); #include <sys/resourcevar.h> int fuswintr(void *base); DESCRIPTION
The fetch functions are designed to copy small amounts of data from user-space. The fetch routines provide the following functionality: fubyte() Fetches a byte of data from the user-space address base. fuword() Fetches a word of data from the user-space address base. fuword16() Fetches 16 bits of data from the user-space address base. fuword32() Fetches 32 bits of data from the user-space address base. fuword64() Fetches 64 bits of data from the user-space address base. fuswintr() Fetches a short word of data from the user-space address base. This function is safe to call during an interrupt context. RETURN VALUES
