The function int rename (const char * old_filename, const char * new_filename) in Library C standard makes filename referenced, changed from old_filename to new_filename.

The void rewind function (FILE * stream) in Standard C library sets the file location to the beginning of the file in the given stream.

The function void setbuf (FILE * stream, char * buffer) in the standard C Library defines how a Stream is buffered. This function should be called once the file attached to the

The function int setvbuf (FILE * stream, char * buffer, int mode, size_t size) in Standard C Library determines how a Stream should be buffered.

Function FILE * tmpfile (void) in standard C Library Create temporary files in wb + mode. The temporary file created will be automatically deleted when the stream is closed

The function char * tmpnam (char * str) in the C Library standard creates and returns a valid temporary file name (temp file) that did not exist before creation. If str is null,

The char * gets (char * str) function in Standard C library reads a line from stdin and stores it inside the string pointed by str. It stops when the end-of-file or newline

The int sprintf function (char * str, const char * format, ...) in the standard C library sends the formatted output to a string str.

The int vfprintf function (FILE * stream, const char * format, va_list arg) in the Standard C library sends the formatted output to a stream using a parameter list.

The function int vsprintf (char * str, const char * format, va_list arg) in the standard C library sends the formatted output to a string string using a parameter list.

The int fscanf function (FILE * stream, const char * format, ...) in Library C reads the input formatted from a Stream.

The function int scanf (const char * format, ...) in Library C standard reads input that has been formatted from stdin.

The function int sscanf (const char * str, const char * format, ...) in Library C standard reads the input formatted from a string.

The function int fgetc (FILE * stream) in C Library standard takes the next character (an unsigned char) from the given Stream and increases the position indicator for that Stream.

Char * fgets (char * str, int n, FILE * stream) in Standard C library reads a line from the given Stream and stores it in the string pointed by str. It stops when any of the

The function int fputc (int char, FILE * stream) in Library C writes one character (an unsigned char) defined by the char parameter to the given Stream and increases the position

The function int fputs (const char * str, FILE * stream) in the Standard C library writes a string to the specified Stream (not writing null characters).

The function int getc (FILE * stream) in C Library standard takes the next character (an unsigned char) from the given Stream and increases the position indicator for that Stream.
