Hi.,

Hi,
In my last thread here, I was able to post without having to wait for approval from a Moderator. Then in my last post. I had a message saying my post has to be approved by a moderator, why?
I hope I didn't break any rules.

I'm new to this. This installer just installs PHP code so NOTHING needs to be built (do I still need to use the build and buildroot directories?). I would just like to create an installer (spec) that:
1) unpacks a tarball
2) moves the unpacked files to the installation target
3) runs a script... (2 Replies)

Hi, we have client in Poland, and they using PB7 as front-end and UNIX at the end. The problem is when they typing in comments field in Polich characters, it goes to host and it got saved in some question marks or some weird format. Does any one know if UNIX can save comments in any languages?... (2 Replies)
GETPGRP(2) BSD System Calls Manual GETPGRP(2)NAME
getpgrp -- get process group
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
pid_t
getpgrp(void);
pid_t
getpgid(pid_t pid);
DESCRIPTION
The process group of the current process is returned by getpgrp(). The process group of the process identified by pid is returned by
getpgid(). If pid is zero, getpgid() returns the process group of the current process.
Process groups are used for distribution of signals, and by terminals to arbitrate requests for their input: processes that have the same
process group as the terminal are foreground and may read, while others will block with a signal if they attempt to read.
This system call is thus used by programs such as csh(1) to create process groups in implementing job control. The tcgetpgrp() and
tcsetpgrp() calls are used to get/set the process group of the control terminal.
RETURN VALUES
The getpgrp() system call always succeeds. Upon successful completion, the getpgid() system call returns the process group of the specified
process; otherwise, it returns a value of -1 and sets errno to indicate the error.
COMPATIBILITY
This version of getpgrp() differs from past Berkeley versions by not taking a pid_t pid argument. This incompatibility is required by
ISO/IEC 9945-1:1990 (``POSIX.1'').
From the ISO/IEC 9945-1:1990 (``POSIX.1'') Rationale:
4.3BSD provides a getpgrp() system call that returns the process group ID for a specified process. Although this function is used to support
job control, all known job-control shells always specify the calling process with this function. Thus, the simpler AT&T System V UNIX
getpgrp() suffices, and the added complexity of the 4.3BSD getpgrp() has been omitted from POSIX.1. The old functionality is available from
the getpgid() system call.
ERRORS
The getpgid() system call will succeed unless:
[ESRCH] there is no process whose process ID equals pid
SEE ALSO getsid(2), setpgid(2), termios(4)STANDARDS
The getpgrp() system call is expected to conform to ISO/IEC 9945-1:1990 (``POSIX.1'').
HISTORY
The getpgrp() system call appeared in 4.0BSD. The getpgid() system call is derived from its usage in AT&T System V Release 4 UNIX.
