| fclose | The fclose function closes stream. | Examples |
| feof | The feof routine determines whether the end of stream has been reached. When end of file is reached, read operations return an end-of-file indicator until the stream is closed. | Examples |
| ferror | The ferror routine tests for a reading or writing error on the file associated with stream. If an error has occurred, the error indicator for the stream remains set until the stream is closed or rewound, or until clearerr is called against it. | Examples |
| fflush | The fflush function flushes a stream. | Examples |
| fgetc | Reads a single character from the current position of a file associated with stream. | Examples |
| fgets | Reads a string from the input stream argument and stores it in string. | Examples |
| fopen | Opens the file specified by filename. | Examples |
| fprintf | Formats and prints a series of characters and values to the output stream. | Examples |
| fputc | Each of these functions writes the single character c to a file. | Examples |
| fputs | This function copies string to the output stream at the current position. | Examples |
| fread | Reads up to count items of size bytes from the input stream and stores them in buffer. | Examples |
| fscanf | Reads data from the current position of stream into the locations given by argument | Examples |
| fseek | Moves the file pointer (if any) associated with stream to a new location that is offset bytes from origin. | Examples |
| ftell | Gets the current position of the file pointer (if any) associated with stream. | Examples |
| fwrite | Writes up to count items, of size length each, from buffer to the output stream. | Examples |
