This project contains two C language programs demonstrating file transfer between processes using shared memory in UNIX/Linux systems. The programs are capable of transferring both text and binary files.
The sender program is designed to send a file to shared memory. It opens a specified file, reads its contents, and copies it into the shared memory, where it can be read by the receiver program.
./sender <file_path><file_path>: Path to the file to be sent.
The receiver program reads data from shared memory, sent by the sender, and writes it to a specified file. It waits for the start of data transmission and continues reading until it receives a signal that the transmission is complete.
./receiver <shared_memory_key> <dest_file><shared_memory_key>: The key of the shared memory used for data transfer.<dest_file>: Path to the file where the received data will be written.
Data is transferred through shared memory, where sender writes data to memory and receiver reads from it. This method allows for efficient data transfer between processes without the need for intermediate files.
To build each of the programs, use gcc:
gcc -o sender sender.c
gcc -o receiver receiver.c After compiling, first start receiver, specifying the shared memory key and the file path for writing, then start sender, specifying the file path of the file to be transferred.
