[c]Why first file is creating after the second. How to avoid
Hi,
My Code is as below:
Here fic_sortie associated file is sometimes created after the file with .balise extension.[x:1000].
What is the bug here in this code.
Hi,
My ubuntu flavor always create temporary files having filename followed by ~ on editing. For eg: if I am editing a file called "sip.c", automatically a temporary (bkup) file is getting created with the name "sip.c~". How to avoid this file creation? (7 Replies)

Good afternoon.
I am a newbie.
We just had a potentially big problem (negated to having good backups).
Basically, there is an option in SAM, to delete all the data from the system that a user ever created.
Lo and behold, silly me, I choose that option, and all sorts of needed files... (5 Replies)

STDIO(3S)STDIO(3S)NAME
stdio - standard buffered input/output package
SYNOPSIS
#include <stdio.h>
FILE *stdin;
FILE *stdout;
FILE *stderr;
DESCRIPTION
The functions described in section 3S constitute a user-level buffering scheme. The in-line macros getc and putc(3S) handle characters
quickly. The higher level routines gets, fgets, scanf, fscanf, fread, puts, fputs, printf, fprintf, fwrite all use getc and putc; they can
be freely intermixed.
A file with associated buffering is called a stream, and is declared to be a pointer to a defined type FILE. Fopen(3S) creates certain
descriptive data for a stream and returns a pointer to designate the stream in all further transactions. There are three normally open
streams with constant pointers declared in the include file and associated with the standard open files:
stdin standard input file
stdout standard output file
stderr standard error file
A constant `pointer' NULL(0) designates no stream at all.
An integer constant EOF (-1) is returned upon end of file or error by integer functions that deal with streams.
Any routine that uses the standard input/output package must include the header file <stdio.h> of pertinent macro definitions. The func-
tions and constants mentioned in sections labeled 3S are declared in the include file and need no further declaration. The constants, and
the following `functions' are implemented as macros; redeclaration of these names is perilous: getc, getchar, putc, putchar, feof, ferror,
fileno.
SEE ALSO open(2), close(2), read(2), write(2), fread(3S), fseek(3S), f*(3S)
DIAGNOSTICS
The value EOF is returned uniformly to indicate that a FILE pointer has not been initialized with fopen, input (output) has been attempted
on an output (input) stream, or a FILE pointer designates corrupt or otherwise unintelligible FILE data.
For purposes of efficiency, this implementation of the standard library has been changed to line buffer output to a terminal by default and
attempts to do this transparently by flushing the output whenever a read(2) from the standard input is necessary. This is almost always
transparent, but may cause confusion or malfunctioning of programs which use standard i/o routines but use read(2) themselves to read from
the standard input.
In cases where a large amount of computation is done after printing part of a line on an output terminal, it is necessary to fflush(3S) the
standard output before going off and computing so that the output will appear.
BUGS
The standard buffered functions do not interact well with certain other library and system functions, especially vfork and abort.
