Hi everybody,

I am faceing problem with strings.

The code is given bellow .In this program i am tring to copy data from
a file into structure .
I am able to copy the data ,but the dat is needed to run some commands
,as u can see i have a string which has the command.

The command is---- chicmd debug 0xB701 0x000000ce3 0xAABBCCDD
I have to repalce the AABBCCDD withe data which is fetched from the
file.
In my program I am tring to fetch one string from the array "cmdbuffer
" the string is "AABBCCDD" with the dat which is fetched form the file
, which is "info->homid".
by using strstr() I am able to fetch the string an replce with it with
the intended one.But its only one time .

Why don't you use sprintf() to build the command string? E.G.:

char cmdstr[100];
char format[] = "chicmd debug 0xB701 0x000000ce3 0x%s";

.
.
.
sprintf( cmdstr, format, "00815002" );

Replace the string constant above with your input from the file.


I am getting this out put -------


chicmd debug 0xB701 0x000000ce3 0x00815000
00815002
00815002
Segmentation fault

When the progarm comes to 2 nd loop its throughing the segmentation
fault error.
I hope this due to the fact that the data in the array is modified
infirst loop and when strstr chels for the string it returns NULL for
failure .


Can any body suggest me how to over come this problem.


int main( int argc ,char *argv[])
{
int ret_code = 0;



//char l_msg[1024];
char * subptr = NULL;
//char cmdbuffer[150]="chicmd debug 0xB701 0x000000ce3
0xAABBCCDD";
char cmdbuffer[150];
char newcmd[512];
char homid[1024];
int8_t ret_c;
int8_t minimal_res = 1;
int8_t resource_no=4;
int8_t loop_size = 4;
//loop_size = Count_all();
//int8_t offset;
//int8_t str_len;
//resource_no = loop_size;
int counter = 0;
//int8_t res_count_deconfig = 0;

/*ret_c = Doreset();
if ( ret_c != 0)
{

//TCFCOMMENT("unable to reset");
}*/

ret_code = Gethom_id();

while(info->next!=NULL){
if(counter <= loop_size)
{
printf("%s\n",info->homid);
sprintf(homid,"%s",info->homid);
printf("%s\n",homid);
cmdbuffer[150]="chicmd debug 0xB701 0x000000ce3
0xAABBCCDD";
subptr = malloc(sizeof(char));
subptr = strstr(cmdbuffer,"0xAABBCCDD");

printf("hello");
subptr[2]=homid[0];
subptr[3]=homid[1];
subptr[4]=homid[2];
subptr[5]=homid[3];
subptr[6]=homid[4];
subptr[7]=homid[5];
subptr[8]=homid[6];
subptr[9]=homid[7];
sprintf(newcmd,"%s",cmdbuffer);

printf("%s\n",newcmd);
}
counter++;
info=info->next;
}

free(info);
return 0;
}

Thanks in advance
