.Dd June 4, 1993 .Dt FCLOSE 3 .Os .Sh NAME .Nm fclose , .Nm fcloseall .Nd close a stream .Sh LIBRARY .Lb libc .Sh SYNOPSIS n stdio.h .Ft int .Fn fclose "FILE *stream" .Ft void .Fn fcloseall void .Sh DESCRIPTION The .Fn fclose function dissociates the named .Fa stream from its underlying file or set of functions. If the stream was being used for output, any buffered data is written first, using .Xr fflush 3 .
p The .Fn fcloseall function calls .Fn fclose on all open streams. .Sh RETURN VALUES Upon successful completion 0 is returned. Otherwise, .Dv EOF is returned and the global variable .Va errno is set to indicate the error. In either case no further access to the stream is possible. .Sh ERRORS The .Fn fclose function may also fail and set .Va errno for any of the errors specified for the routines .Xr close 2 or .Xr fflush 3 . .Sh NOTES The .Fn fclose function does not handle NULL arguments; they will result in a segmentation violation. This is intentional - it makes it easier to make sure programs written under .Fx are bug free. This behaviour is an implementation detail, and programs should not rely upon it. .Sh SEE ALSO .Xr close 2 , .Xr fflush 3 , .Xr fopen 3 , .Xr setbuf 3 .Sh STANDARDS The .Fn fclose function conforms to .St -isoC .
p The .Fn fcloseall function first appeared in .Fx 7.0 .
