I have two process to do the same thing, how to organize the access to the file where each process 'll write.
there is C++ code :
FILE * pFile;
pFile = fopen ("wirelessRecv.tr","a+"); ( the same file for the two process)
macmib_.ReceivedFragmentCount++; (each process have a counter )
fprintf (pFile, "\n "TIME_FORMAT" %d %d %d" ,
