FETCH(9) BSD Kernel Developer's Manual FETCH(9)NAME
fetch, fubyte, fuibyte, fuiword, fulong, fuulong, fuword -- fetch data from user-space
SYNOPSIS
#include <sys/types.h>
#include <sys/time.h>
#include <sys/systm.h>
#include <sys/resourcevar.h>
int
fubyte(const user_addr_t addr);
int
fuibyte(const user_addr_t addr);
int
fuiword(user_addr_t addr);
int64_t
fulong(user_addr_t addr);
uint64_t
fuulong(user_addr_t addr);
int
fuword(user_addr_t addr);
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 addr.
fuibyte() Fetches a byte of data from the user-space address addr. This function is safe to call during an interrupt context.
fuiword() Fetches a word of data from the user-space address addr. This function is safe to call during an interrupt context.
fulong() Fetches a long word of data from the user-space address addr.
fuulong() Fetches a unsigned long word of data from the user-space address addr.
fuword() Fetches a word of data from the user-space address addr.
RETURN VALUES
The fetch functions return the data fetched or -1 on failure.

Hi,
I would want to fetch all the numbers after a word the number of characters could very. how can I do that?
below is the example of the data and the expected output
sample data
03 xxxx occurs 1090 times.
04 aslkja occurs 10 times.
I would want to fetch 10 & 1090 separately. (13 Replies)
Hi,
I got a requirement to fetch data between two time stamps in a big log file and grep for a word in that particular time interval of data.
Here is my log looks like:
