Hi All,
My main intension of is to convert the Hexstring stored in a char* into hex and then prefixing it with "0x" and suffix it with ','
This has to be done for all the hexstring char* is NULL.
Store the result prefixed with "0x" and suffixed with ',' in another char* and pass it to... (1 Reply)
Hi,
Is there really a difference between these two, std::hex and ios::hex??
I stumbled upon reading a line, "std::ios::hex is a bitmask (8 on gcc) and works with setf(). std::hex is the operator". Is this true?
Thanks (0 Replies)
Hi,
I want to split/parse certain bits of the hex data into another field.
Example:
Input data is
Word1: 4f72abfd
Output:
Parse bits (5 to 0) into field word1data1=0x00cd=205 decimal
Parse bits (7 to 6) into field word1data2=0x000c=12 decimal
etc.
Word2: efff3d02
Parse bits (13 to... (1 Reply)

Hi guys,
First off, i'm a complete noob to UNIX and LINUX so apologies if I don't understand the basics!
I have a file which contains a hex value of '0D' at the end of each line when I look at it in a hex viewer.
I need to change it so it contains a hex value of '0D0A0A'
I thought... (10 Replies)
dHi,
I have the attached file(actual file can be extracted post unzipping it) & i am trying to use the following code for coversion to hex format.
Starting hex value is 84 which is start of the record & termination is done using 00 00 followed by 84(hex) which i can see in the dump clearly using... (14 Replies)

i386_pmc_startstop
I386_PMC_INFO(2) BSD/i386 System Calls Manual I386_PMC_INFO(2)NAME
i386_pmc_info, i386_pmc_startstop, i386_pmc_read -- interface to CPU performance counters
LIBRARY
i386 Architecture Library (libi386, -li386)
SYNOPSIS
#include <sys/types.h>
#include <machine/sysarch.h>
#include <machine/specialreg.h>
int
i386_pmc_info(struct i386_pmc_info_args *ia);
int
i386_pmc_startstop(struct i386_pmc_startstop_args *ssa);
int
i386_pmc_read(struct i386_pmc_read_args *ra);
DESCRIPTION
These functions provide an interface to the CPU performance counters on the 586-class and 686-class processors.
i386_pmc_info() will return information about the available CPU counters. The information is returned in ia having the following structure:
struct i386_pmc_info_args {
int type;
int flags;
};
The type member describes the class of performance counters available. Valid values are:
PMC_TYPE_NONE No PMC support
PMC_TYPE_I586 586-class CPUs
PMC_TYPE_I686 686-class Intel CPUs
PMC_TYPE_K7 686-class AMD CPUs
The flags member describes additional capabilities of the processor. Valid values are:
PMC_INFO_HASTSC CPU has time-stamp counter
i386_pmc_startstop() is used to start and stop the measurement of the CPU performance counters. The argument ssa has the following struc-
ture:
struct i386_pmc_startstop_args {
int counter;
uint64_t val;
uint8_t event;
uint8_t unit;
uint8_t compare;
uint8_t flags;
};
The counter specified by the member counter is started if the member flags has PMC_SETUP_KERNEL or PMC_SETUP_USER set, otherwise the counter
is stopped. The initial value of the counter is set to val. Additional values for the flags member are PMC_SETUP_EDGE and PMC_SETUP_INV.
The event member specifies some event written to the control register. The unit member specifies the measurement units. The compare member
is a mask for the counter.
i386_pmc_read() will return information about a specific CPU counter measured during the last measurement period determined by the calling of
i386_pmc_startstop(). The information is returned in ra having the following structure:
struct i386_pmc_read_args {
int counter;
uint64_t val;
uint64_t time;
};
The counter to read should be specified by the counter member. Counters are numbered from 0 to PMC_NCOUNTERS. The value of the counter is
returned in the val member. The time since epoch, measured in CPU clock cycles, is returned in the time member.
RETURN VALUES
Upon successful completion zero is returned, otherwise -1 is returned on failure.
