How do you edit a existing file in c program?
Open the file for reading and load the content into memory where it can freely edited. To prevent external changes to the file, keep the file open but lock it to prevent access. When the user saves the modified data, write that data to a temporary file then close it. Then close the original file, delete it and rename the temporary file with the original file name. For added safety during file edits, you should also maintain a recovery file that keeps track of all the changes. Once the temporary is renamed, you can delete the recovery file.
What are the Unix system calls for Input and Output?
In Unix, the primary system calls for input and output are read(), write(), open(), close(), and lseek(). The open() call is used to open a file descriptor for reading or writing, while read() and write() perform the actual data transfer between the file descriptor and a buffer in memory. The close() call is used to close the file descriptor, and lseek() allows for repositioning the file pointer within the file. These calls provide a low-level interface for file and device I/O operations.
