Hi,
I have the following C code, which does the following :-
Takes the brt file name from character 1 of the input filename (ALLSMFAS.ref) and creates a new file (A.brt) as follows :-
ALLSMFAS.ref

a new file is created.
So for input file :-
ALLSMFAS.ref
AD,B,0424,0415,89375,,A,2,,80,,
AD,B,0424,0417,89375,,A,1,,82,,

CC,B,1783,1578,48231,,C,3,,60,,
:
:the following needs to be the output files.
AD.brt
B0424041589375 B0424041789375 B0416041089375BN.brt
B0135009465625 B0338033765824 B0334033965824CA.brt

B1783157448231 B1783157648231 B1783157848231and so on ….
In the above code, I am stuck up at the following place, where I believe the logic for reading the first column of the file
and for each change in the value, a new file is created has to be put.
1234567// Take the brt file name from character 1 of the input filename.<br /><br />memcpy(this_td,<br />wfd.cFileName,<br />1);<br />this_td[2] = 0;<br />Request you, if you could please help me with the appropriate code for this.
Thanks a lot.
Marconi.
