/****** uti/string/sge_jobname() ***********************************************
* NAME
* sge_jobname() -- get jobname of command line string
*
* SYNOPSIS
* const char* sge_jobname(const char *name)
*
* FUNCTION
* Determine the jobname of a command line. The following definition is used
* for the jobname:
* - take everything up to the first semicolon
* - take everything up to the first whitespace
* - take the basename
*
* INPUTS
* const char *name - contains the input string (command line)
*
* RESULT
* const char* - pointer to the jobname
* NULL if name is NULL or only '\0'
*
* EXAMPLE
* Command line jobname
* ----------------------------------------------
* "cd /home/me/5five; hostname" --> cd
* "/home/me/4Ujob" --> 4Ujob (invalid, will be denied)
* "cat /tmp/5five" --> cat
* "bla;blub" --> bla
* "a b" --> a
*
*
* NOTES
* MT-NOTE: sge_jobname() is not MT safe
*
* SEE ALSO
* sge_basename()

*
* 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
