Hello all,
I worte a structure and filled the data, then i need to send them on tcp socket. before that i need to send only few data and i need to split them into bytes and need to store them in other array.
Here is the code below
#include "stdafx.h"
#include <string.h>
#include <malloc.h>
struct Test
{
int sno;
char name[24];
int rno;
} testexmp;
//conversion of structure into bytes
unsigned long int x;
void dumpHex ( void *p, size_t size )
{
//int *list = malloc(n* sizeof(int));
unsigned char *bytes = (unsigned char *)p;
for (size_t i = 0 ; i < size ; i++ )
{
unsigned int b = bytes[i];
if (b>3)
{
/* how to copy the remaining bytes into other array */
printf(" i=%d 0x%02x \n",i,(char*)bytes[i]);
memcpy(&x, bytes, sizeof(long));
}
}
}
int main(int argc, char* argv[])
{
printf("size of the test structure is %d \n",sizeof(testexmp));
testexmp.sno=1;
strcpy(testexmp.name,"testsample");
testexmp.rno=10;
dumpHex(&testexmp,sizeof(testexmp));
printf("sno is %d \n",testexmp.sno);
printf("name is %s \n",testexmp.name);
printf("roll no is %d \n",testexmp.sno);
return 0;
}
