Gregory Nutt	8de513e36b	apps/system/nsh: Move apps/examples/nsh to apps/system/nsh. It has become so entrenched that it is hardly an example these days. May as well formalized it as a system task.	2018-08-18 09:04:43 -06:00
Gregory Nutt	e3e911555a	apps/system/system and popen: Adapt so that these can be used in the KERNEL build mode. In this case, simply replace task_spawn() with posix_spawn(). This depends on the existence of some environment where /bin/sh exists and can be used to execute one NSH command. For the case of system(), this change was more complete because it previously used task_create(). Now it uses either task_spawn() or posix_spawn(), depending upon the configuration.	2018-08-18 07:55:23 -06:00
Gregory Nutt	8455ee34b6	apps/system/popen/Kconfig: popen is not available in the KERNEL build.	2018-08-17 15:58:29 -06:00
Gregory Nutt	064d4024e4	apps/examples/popen: Add a test of popen/pclose. apps/system/popen: Fix some errors found using the new popen/pclose test.	2018-08-17 14:25:33 -06:00
Gregory Nutt	f198e32c17	apps/system/popen: Add an implementation of the standard popen() and pclose() OS interfaces. These are implementated as applications vs. part of the OS because they depend on NSH. Untested on initial commit.	2018-08-17 10:45:06 -06:00
