* Runs a child process and blocks until it returns. Arguments as follows:

*
|
|
* cmd = Command line to run.
|
|
* state = Expected return value of kwsysProcess_GetState after exit.
|
|
* exception = Expected return value of kwsysProcess_GetExitException.
|
|
* value = Expected return value of kwsysProcess_GetExitValue.
|
|
* share = Whether to share stdout/stderr child pipes with our pipes
|
|
* by way of kwsysProcess_SetPipeShared. If false, new pipes
|
|
* are created.
|
|
* output = If !share && !disown, whether to write the child's stdout
|
|
* and stderr output to our stdout.
|
|
* delay = If !share && !disown, adds an additional short delay to
|
|
* the pipe loop to allow the pipes to fill up; Windows only.
|
|
* timeout = Non-zero to sets a timeout in seconds via
|
|
* kwsysProcess_SetTimeout.
|
|
* poll = If !share && !disown, we count the number of 0.1 second
|
|
* intervals where the child pipes had no new data. We fail
|
|
* if not in the bounds of MINPOLL/MAXPOLL.
|
|
* repeat = Number of times to run the process.
|
|
* disown = If set, the process is disowned.
|
|
* createNewGroup = If set, the process is created in a new process group.
|
|
* interruptDelay = If non-zero, number of seconds to delay before
|
|
* interrupting the process. Note that this delay will occur
|
|
* BEFORE any reading/polling of pipes occurs and before any
|
|
* detachment occurs.
