Hi
I am using sun solaris 5.9 operating system.Sometime s after reading from and while writing to file process size used to get increase.(it can be after 20th times 40 th time)
I doesn't happen always but some time.After putting print statements i identified the point.Can any body tell me whether it will going to come in memory leak or normal process usuage.If it comes under memory leak how to slove?I have marked the code below from where it used to get increase.
Appreciate ur input in this.I have tried flushing out o/p buffer.But result is same.
Waiting for any input.......... .....

Hi,
I have an array of data (which I am getting from a socket connection).
I am working on a program which acts on this data but the program is
written to work on data from a file (not from an array). I cannot
change anything in the program but can add some features by which I
can convert this array of data into a file. The easiest thing would be
to write the data into a file (in hard disk) and use it. But I will be

I wrote this code just to experiment with writing to and reading from a
file. It seems to work fine when writing, but when reading the file, it
only prints the filepath to the screen, not the file contents.
System.IO.StreamWriter file = new
System.IO.StreamWriter(@"C:\positions.txt");
System.IO.StringReader myFile = new
System.IO.StringReader(@"C:\positions.txt");

Hi there,
I am trying to read from a file and at the same time change certain
fields of the same field, there are 6 fields in this file like
1 2 3 4 5 6

For example, I position my file pointer at the begining of the 4th
fileld lets say 25th character(3*(field_width)+1) and when I try to

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
