Solution

If your problem is regarding text data means the following may be the problem,

1. It may be the buffer problem.You need to flush the buffers like stdin,stdout after sending and receiving the data.

2 .You should have the buffer size which is enough to hold your data.For example ,if you are getting the input data in a variable called buf[100].So your data should have the maximum 100 characters which includes the null character to terminate the string .
