2.1.9 File IO
Functions
Name
Brief
Example
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.
