hey everyone!
got another problem here.
how would i use the getchar() in a prompt:
Press any key to continue
the way i did it was to define a char variable named ch
and then wrotechar ch
...
ch = getchar();
printf("Press any key to continue");
getchar():if you press enter it exits, but... (2 Replies)

There's a replacement in bash for getchar or get functions of C and C++?Those functions read the next char avaliable in the input stream.
I've tried something like:
OLD_STTY=`stty -g`
stty cbreak -echo
look=`dd if=/dev/tty bs=1 count=1 2>/dev/null`
stty $OLD_STTY
But it is not working... (3 Replies)

I wanted to make a simple program that writes chracters in a file but i didnt want to press enter .So i found the getchar which doesnt need enter.If i pass (int) getchar to putc ,in the file it shows a P character.The (int) getchar says it is equal to1734747216 so i do (int) getchar-1734747216...

Hi,
What happens to process state when getchar() is called? I wrote a C code in which I call getchar() somewhere down the road. I forgot about that, I started the process, put it in bg and disowned it using "disown". Now, how do I see where that process has gone/how do kill it?
Thanks,

Hi all,
i'm trying to configure a script that will find and gzip the searched files,
this is easy enough,
find /var/log/myfolder/*.log -type f -mtime +1 -exec gzip {} \;
cd /var/log/myfolder/
mv *gz myzipped_folder/
but what it would be very handy is to skip the files in use,because tomcat... (13 Replies)

fgetc
GETC(3) BSD Library Functions Manual GETC(3)NAME
fgetc, getc, getchar, getc_unlocked, getchar_unlocked, getw -- get next character or word from input stream
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <stdio.h>
int
fgetc(FILE *stream);
int
getc(FILE *stream);
int
getchar();
int
getc_unlocked(FILE *stream);
int
getchar_unlocked();
int
getw(FILE *stream);
DESCRIPTION
The fgetc() function obtains the next input character (if present) from the stream pointed at by stream, or the next character pushed back on
the stream via ungetc(3).
The getc() function acts essentially identically to fgetc(), but is a macro that expands in-line.
The getchar() function is equivalent to: getc with the argument stdin.
The getc_unlocked() and getchar_unlocked() functions provide functionality identical to that of getc() and getchar(), respectively, but do
not perform implicit locking of the streams they operate on. In multi-threaded programs they may be used only within a scope in which the
stream has been successfully locked by the calling thread using either flockfile(3) or ftrylockfile(3), and may later be released using
funlockfile(3).
The getw() function obtains the next int (if present) from the stream pointed at by stream.
RETURN VALUES
If successful, these routines return the next requested object from the stream. If the stream is at end-of-file or a read error occurs, the
routines return EOF. The routines feof(3) and ferror(3) must be used to distinguish between end-of-file and error. If an error occurs, the
global variable errno is set to indicate the error. The end-of-file condition is remembered, even on a terminal, and all subsequent attempts
to read will return EOF until the condition is cleared with clearerr(3).
SEE ALSO ferror(3), flockfile(3), fopen(3), fread(3), ftrylockfile(3), funlockfile(3), putc(3), ungetc(3)STANDARDS
The fgetc(), getc() and getchar() functions conform to ANSI X3.159-1989 (``ANSI C89''). The getc_unlocked() and getchar_unlocked() functions
conform to ISO/IEC 9945-1:1996 (``POSIX.1'').
BUGS
Since EOF is a valid integer value, feof(3) and ferror(3) must be used to check for failure after calling getw(). The size and byte order of
an int varies from one machine to another, and getw() is not recommended for portable applications.
