/****** uti/stdio/sge_peopen() ************************************************
* NAME
* sge_peopen_r() -- Advanced popen()
*
* SYNOPSIS
* pid_t sge_peopen_r(const char *shell, int login_shell,
* const char *command, const char *user,
* char **env, FILE **fp_in, FILE **fp_out,
* FILE **fp_err)
*
* FUNCTION
* Advanced popen() with additional parameters:
* - free shell usage
* - login shell if wanted
* - user under which to start (for root only)
* - stdin and stderr file pointers
* - wait for exactly the process we started
* File descriptors have to be closed with sge_peclose().
*
* This function is reentrant as long as env is not provided to
* this function. This means that the function can be used in
* multi thread processed as long as env is not used.
*
* INPUTS
* const char *shell - which shell to use
* int login_shell - make it a login shell?
* const char *command - name of the program
* const char *user - user under which to start (for root only)
* char **env - env variables to add to child
* FILE **fp_in - file input stream
* FILE **fp_out - file output stream
* FILE **fp_err - file error stream
*
* RESULT
* pid_t - process id
*
* NOTES
* MT-NOTE: sge_peopen() is MT safe
*
* DO NOT ADD ASYNC SIGNAL UNSAFE FUNCTIONS BETWEEN FORK AND EXEC
* DUE TO THE FACT THAT THIS FUNCTION WILL BE USED IN QMASTER
* (MULTITHREADED ENVIRONMENT) THIS MIGHT CAUSE A DEADLOCK
* IN A MASTER THREAD.
*
* SEE ALSO
* uti/stdio/sge_peclose()

/****** Interactive/qrsh/startJob() ***************************************
*
* NAME
* startJob() -- start a shell with commands to execute
*
* SYNOPSIS
* static int startJob(char *command, char *wrapper, int noshell);
*
* FUNCTION
* Starts the commands and arguments to be executed as
* specified in parameter <command>.
* If the parameter noshell is set to 1, the command is directly called
* by exec.
* If a wrapper is specified (parameter wrapper, set by environment
* variable QRSH_WRAPPER), this wrapper is called and is passed the
* command to execute as commandline parameters.
* If neither noshell nor wrapper is set, a users login shell is called
* with the parameters -c <command>.
* The child process creates an own process group.
* The pid of the child process is written to a pid file in $TMPDIR.
*
* INPUTS
* command - commandline to be executed
* wrapper - name and path of a wrapper script
* noshell - if != 0, call the command directly without shell
*
* RESULT
* status of the child process after it terminated
* or EXIT_FAILURE, if the process of starting the child
* failed because of one of the following error situations:
* - fork failed
* - the pid of the child process cannot be written to pid file
* - the name of actual user cannot be determined
* - info about the actual user cannot be determined (getpwnam)
* - necessary memory cannot be allocated
* - executing the shell failed
*
* SEE ALSO
* Interactive/qrsh/write_pid_file()
* Interactive/qrsh/split_command()
* Interactive/qrsh/join_command()
