Function

Navn	Beskrivelse
int asprintf (char *__restrict __ptr, __const char __restrict __fmt, ...) __THROW __attribute__ ((__format__ (__printf__, 2, 3)));	Write formatted output to a string dynamically allocated with `malloc'. Store the address of the string in *PTR.
int dprintf (int __fd, __const char *__restrict __fmt, ...) __THROW __attribute__ ((__format__ (__printf__, 2, 3)));	Write formatted output to a file descriptor.
int fclose (FILE *__stream) __THROW;	Close STREAM.
int fcloseall (void) __THROW;	Close all streams.
FILE *fdopen (int __fd, __const char *__modes) __THROW;	Create a new stream that refers to an existing system file descriptor.
int fflush (FILE *__stream) __THROW;	Flush STREAM, or all streams if STREAM is NULL.
int fflush_unlocked (FILE *__stream) __THROW;	Faster versions when locking is not required.
FILE *fmemopen (void __s, size_t __len, __const char __modes) __THROW;	Create a new stream that refers to a memory buffer.
FILE *fopen (__const char __restrict __filename, __const char __restrict __modes) __THROW;	Open a file and create a new stream for it.
FILE *fopencookie (void __restrict __magic_cookie, __const char __restrict __modes, _IO_cookie_io_functions_t __io_funcs) __THROW;	Create a new stream that refers to the given magic cookie, and uses the given functions for input and output.
int printf (__const char *__restrict __format, ...) __THROW;	Write formatted output to stdout.
int fprintf (FILE __restrict __stream, __const char __restrict __format, ...) __THROW;	Write formatted output to STREAM.
FILE *freopen (__const char __restrict __filename, __const char __restrict __modes, FILE *__restrict __stream) __THROW;	Open a file, replacing an existing stream with it.
int fscanf (FILE __restrict __stream, __const char __restrict __format, ...) __THROW;	Read formatted input from STREAM.
FILE *open_memstream (char *__restrict __bufloc, size_t __restrict __sizeloc) __THROW;	Open a stream that writes into a malloc'd buffer that is expanded as necessary. BUFLOC and SIZELOC are updated with the buffer's location and the number of characters written on fflush or fclose.
int remove (__const char *__filename) __THROW;	Remove file FILENAME
int rename (__const char __old, __const char __new) __THROW;	Rename file OLD to NEW.
int scanf (__const char *__restrict __format, ...) __THROW;	Read formatted input from stdin.
void setbuf (FILE __restrict __stream, char __restrict __buf) __THROW;	If BUF is NULL, make STREAM unbuffered. Else make it use buffer BUF, of size BUFSIZ.
int setvbuf (FILE __restrict __stream, char __restrict __buf, int __modes, size_t __n) __THROW;	Make STREAM use buffering mode MODE. If BUF is not NULL, use N bytes of it for buffering; else allocate an internal buffer N bytes long.
int sprintf (char __restrict __s, __const char __restrict __format, ...) __THROW;	Write formatted output to S.
int snprintf (char __restrict __s, size_t __maxlen, __const char __restrict __format, ...) __THROW __attribute__ ((__format__ (__printf__, 3, 4)));	Maximum chars of output to write in MAXLEN.
int sscanf (__const char __restrict __s, __const char __restrict __format, ...) __THROW;	Read formatted input from S.
FILE *tmpfile (void) __THROW;	Create a temporary file and open it read/write.
char *tmpnam (char *__s) __THROW;	Generate a temporary filename.
int vasprintf (char *__restrict __ptr, __const char __restrict __f, _G_va_list __arg) __THROW __attribute__ ((__format__ (__printf__, 2, 0)));	Write formatted output to a string dynamically allocated with `malloc'. Store the address of the string in *PTR.
int vdprintf (int __fd, __const char *__restrict __fmt, _G_va_list __arg)	Write formatted output to a file descriptor.
int vfprintf (FILE __restrict __s, __const char __restrict __format, _G_va_list __arg) __THROW;	Write formatted output to S from argument list ARG.
int vfscanf (FILE __restrict __s, __const char __restrict __format, _G_va_list __arg) __THROW __attribute__ ((__format__ (__scanf__, 2, 0)));	Read formatted input from S into argument list ARG.
int vprintf (__const char *__restrict __format, _G_va_list __arg) __THROW;	Write formatted output to stdout from argument list ARG.
int vsprintf (char __restrict __s, __const char __restrict __format, _G_va_list __arg) __THROW;	Write formatted output to S from argument list ARG.
int vsnprintf (char __restrict __s, size_t __maxlen, __const char __restrict __format, _G_va_list __arg) __THROW __attribute__ ((__format__ (__printf__, 3, 0)));	Maximum chars of output to write in MAXLEN.
int vscanf (__const char *__restrict __format, _G_va_list __arg) __THROW __attribute__ ((__format__ (__scanf__, 1, 0)));	Read formatted input from stdin into argument list ARG.
int vsscanf (__const char __restrict __s, __const char __restrict __format, _G_va_list __arg) __THROW __attribute__ ((__format__ (__scanf__, 2, 0)));	Read formatted input from S into argument list ARG.
int __asprintf (char *__restrict __ptr, __const char __restrict __fmt, ...) __THROW __attribute__ ((__format__ (__printf__, 2, 3)));	Write formatted output to a string dynamically allocated with `malloc'. Store the address of the string in *PTR.
