<h2>Developing your own utilities</h2>
|
||
|
|
|
||
|
|
<p>You can develop your own
|
||
|
|
utility programs using any language, although ILE/C, ILE/C++, and
|
||
|
|
Java have the best runtime support. When creating ILE/C or ILE/C++
|
||
|
|
programs, you should use Integrated File System I/O when creating
|
||
|
|
all of the modules in your utility program.</p>
|
||
|
|
|
||
|
|
<p>A utility reads input from standard input or descriptor 0,
|
||
|
|
writes output to standard output or descriptor 1, and writes errors
|
||
|
|
to standard error or descriptor 2.</p>
|
||
|
|
|
||
|
|
<p>If your utility program uses the ILE/C or ILE/C++ standard files
|
||
|
|
for I/O, you can run your utility from either the <strong>
|
||
|
|
qsh</strong> command line or the QCMD command line. If your utility
|
||
|
|
reads and writes directly from descriptors 0, 1, and 2, you can
|
||
|
|
only run your utility from the Qshell command line.</p>
