<h2>Qp0zSystem()--Run a CL Command</h2>

Syntax<br>
|

<pre>
|

#include <qp0z1170.h>
|
|
|
|
int Qp0zSystem( const char <em>*CLcommand</em> );

|
|
<p>The <strong>Qp0zSystem()</strong> function spawns a new process, passes <em>
|
|
CLcommand</em> to the CL command processor in the new process, and waits for
|
|
the command to complete. The command runs in a batch job so it does not have
|
|
access to a terminal.</p>
|
|
|
|
<p>This function is similar to the <strong>system()</strong> function provided
|
|
by ILE C, but allows a program to safely run a CL command from a multithreaded
|
|
process. Note that if <em>CLcommand</em> fails, the global variable _EXCP_MSGID
|
|
is not set with the exception message id.</p>
|
|
|
|

|
|
<h3>Parameters</h3>
|
|
|
|
<dl>
|
|
<dt><strong><em>*CLcommand</em></strong></dt>
|
|
|
|
<dd>(Input) Pointer to null-terminated CL command string.</dd>
|
|
</dl>
|
|
|
|
<br>
|
|
<h3>Authorities</h3>
|
|
|
|
<p>The user calling <strong>Qp0zSystem()</strong> must have *USE authority to
|
|
the specified CL command.</p>

<p>The following example shows how to use the <strong>Qp0zSystem()</strong>
|
|
function to create a library.</p>
|
|
|
|
<pre>
|
|
#include <stdio.h>
|
|
#include <qp0z1170.h>
|
|
|
|
int main(int argc, char *argv[])
|
|
{
|
|
if (Qp0zSystem("CRTLIB LIB(XYZ)") != 0)
|
|
printf("Error creating library XYZ.\n");
|
|
else
|
|
printf("Library XYZ created.\n");
|
|
|
|
return(0);
|
|
}
|
|
|
|
</pre>
|
|
