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)

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 {} \;

cap_fcntls_get
CAP_FCNTLS_LIMIT(2) BSD System Calls Manual CAP_FCNTLS_LIMIT(2)NAME
cap_fcntls_limit, cap_fcntls_get -- manage allowed fcntl commands
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <sys/capsicum.h>
int
cap_fcntls_limit(int fd, uint32_t fcntlrights);
int
cap_fcntls_get(int fd, uint32_t *fcntlrightsp);
DESCRIPTION
If a file descriptor is granted the CAP_FCNTL capability right, the list of allowed fcntl(2) commands can be selectively reduced (but never
expanded) with the cap_fcntls_limit() system call.
A bitmask of allowed fcntls commands for a given file descriptor can be obtained with the cap_fcntls_get() system call.
FLAGS
The following flags may be specified in the fcntlrights argument or returned in the fcntlrightsp argument:
CAP_FCNTL_GETFL Permit F_GETFL command.
CAP_FCNTL_SETFL Permit F_SETFL command.
CAP_FCNTL_GETOWN Permit F_GETOWN command.
CAP_FCNTL_SETOWN Permit F_SETOWN command.
RETURN VALUES
Upon successful completion, the value 0 is returned; otherwise the value -1 is returned and the global variable errno is set to indicate the
error.
ERRORS
cap_fcntls_limit() succeeds unless:
[EBADF] The fd argument is not a valid descriptor.
[EINVAL] An invalid flag has been passed in fcntlrights.
[ENOTCAPABLE] fcntlrights would expand the list of allowed fcntl(2) commands.
cap_fcntls_get() succeeds unless:
[EBADF] The fd argument is not a valid descriptor.
[EFAULT] The fcntlrightsp argument points at an invalid address.
