Misc values

[rm_titus]

Hello all,

 

I would like to modify miscellaneous values through the binary NCI data.

I'm able to parse the whole binary file using the function nci_manager() in combination with the flag NCIMGR_RD.

For each (gcode==1011 || gcode==1012) I'm trying to write something into each misc member. The code goes like:

 

code:

---

	nci_manager (0, NCIMGR_RD, &n, &fpos, &succf);   

if(n.gcode==1011)

{

memset (&nci_line, 0, sizeof (nci_bin));

nci_line.u.m1011.misc[0] = 4.0;

.....

nci_line.u.m1011.misc[9] = 4.0;

nci_manager (0, NCIMGR_WR, &nci_line, &fpos, &succf);

}

else if(n.gcode==1012)

{

memset (&nci_line, 0, sizeof (nci_bin));

nci_line.u.m1011.misc[0] = 5;

.....

nci_line.u.m1011.misc[9] = 5;

nci_manager (0, NCIMGR_WR, &nci_line, &fpos, &succf);

}

---

The difficulty I'm having is that using the flag NCIMGR_WR doesn't write anything at the current position.

 

Am I miss something ?!

 

Thanks a lot !!

Nobody answer me .... any guru wants to give me a hint ?

 

Thank you !

sorry. I wish I could help out but, I don't know. The few times I tried playing with binary nci stuff I blew up the computer real good.

One potential cause for your problem might be that the way the code is set up, your writing the op after itself. (Doing a read and then a write...)

You should be able to get around this by inserting the following BEFORE your NCIMGR_RD statement...

 

long previousFPOS = fpos;

 

and then adding this BEFORE your NCIMGR_WR statement...

 

(void)fseek (fnci_bin, previousFPOS, SEEK_SET);

 

This should position the binary NCI file back at the location you read from.

Sorry Titus, I didnt answer your mail..

 

I did not have any idea of calling fseek().

I thought it would write the data at the position..

nci_manager (0, NCIMGR_WR, &nci_line, &fpos_prevpos, &succf);

 

Thanks Pete!!!12

Hi guys,

 

Your suggestions has solved a BIG part of the problem and I'd like to share the specific code with others but is a bit longer to put it on the forum. If you ever need it, please don't hesitate to send me an email....

 

Thank you all!

Titus
