fcloseall(3) Library Functions Manual fcloseall(3)
fcloseall - close all open streams
Standard C library (libc, -lc)
#define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h> int fcloseall(void);
The fcloseall() function closes all of the calling process's open streams. Buffered output for each stream is written before it is closed (as for fflush(3)); buffered input is discarded. The standard streams, stdin, stdout, and stderr are also closed.
This function returns 0 if all files were successfully closed; on error, EOF is returned.
For an explanation of the terms used in this section, see attributes(7). ┌───────────────────────┬───────────────┬────────────────────────┐ │Interface │ Attribute │ Value │ ├───────────────────────┼───────────────┼────────────────────────┤ │fcloseall() │ Thread safety │ MT-Unsafe race:streams │ └───────────────────────┴───────────────┴────────────────────────┘ The fcloseall() function does not lock the streams, so it is not thread-safe.
