read function
Hello all
In UNIX i wrote a program which simply establishes a conncetion with another system, using write system call i wrote a message to the server from client and from the server i send another message, for the second time i send a mesage using write system call to the server, when i send a message from the server using write system call for the second time iam not able to read in the client , the client waits in an infinite loop. what is the problem in using repeated read or write calls subsequently
plz explain my doubt

I use fopen, fscanf, fclose to read a file. It can work well. since many files should be read, a function is created with the same code. But in the function, fscanf can not work well.
for example, the first line of the the file is: > filename
but the fscanf will give: 207/23/eee/34

mosh-client
MOSH(1) General Commands Manual MOSH(1)
NAME
mosh-client - client-side helper for mosh
SYNOPSIS
MOSH_KEY=KEY mosh-client IP PORT
mosh-client -c
DESCRIPTION
mosh-client is a helper program for the mosh(1) remote terminal application.
mosh itself is a setup script that establishes an SSH connection, runs the server-side helper mosh-server, and collects the server's port
number and session key.
mosh then executes mosh-client with the server's IP address, port, and session key. mosh-client runs for the lifetime of the connection.
The 22-byte base64 session key given by mosh-server is supplied in the MOSH_KEY environment variable. This represents a 128-bit AES key
that protects the integrity and confidentiality of the session.
For constructing new setup wrappers for remote execution facilities other than SSH, it may be necessary to invoke mosh-client directly.
With the -c option, mosh-client instead prints the number of colors of the terminal given by the TERM environment variable.
