* Name: posix_spawn
*
* Description:
* The posix_spawn() and posix_spawnp() functions will create a new,
* child task, constructed a regular executable file.
*
* Input Parameters:
*
* pid - Upon successful completion, posix_spawn() and posix_spawnp() will
* return the task ID of the child task to the parent task, in the
* variable pointed to by a non-NULL 'pid' argument. If the 'pid'
* argument is a null pointer, the process ID of the child is not
* returned to the caller.
*
* path - The 'path' argument to posix_spawn() is the absolute path that
* identifies the file to execute. The 'path' argument to posix_spawnp()
* may also be a relative path and will be used to construct a pathname
* that identifies the file to execute. In the case of a relative path,
* the path prefix for the file will be obtained by a search of the
* directories passed as the environment variable PATH.
*
* NOTE: NuttX provides only one implementation: If
* CONFIG_BINFMT_EXEPATH is defined, then only posix_spawnp() behavior
* is supported; otherwise, only posix_spawn behavior is supported.
*
* file_actions - If 'file_actions' is a null pointer, then file
* descriptors open in the calling process will remain open in the
* child process (unless CONFIG_FDCLONE_STDIO is defined). If
* 'file_actions' is not NULL, then the file descriptors open in the
* child process will be those open in the calling process as modified
* by the spawn file actions object pointed to by file_actions.
*
* attr - If the value of the 'attr' parameter is NULL, the all default
* values for the POSIX spawn attributes will be used. Otherwise, the
* attributes will be set according to the spawn flags. The
* posix_spawnattr_t spawn attributes object type is defined in spawn.h.
* It will contains these attributes, not all of which are supported by
* NuttX:
*
* - POSIX_SPAWN_SETPGROUP: Setting of the new tasks process group is
* not supported. NuttX does not support process groups.
* - POSIX_SPAWN_SETSCHEDPARAM: Set new tasks priority to the sched_param
* value.
* - POSIX_SPAWN_SETSCHEDULER: Set the new tasks scheduler priority to
* the sched_policy value.
* - POSIX_SPAWN_RESETIDS: Resetting of effective user ID of the child
* process is not supported. NuttX does not support effective user
* IDs.
* - POSIX_SPAWN_SETSIGMASK: Setting the initial signal mask of the new
* task is not supported. NuttX does support signal masks, but there
* is no mechanism in place now to do this.
* - POSIX_SPAWN_SETSIGDEF: Resetting signal default actions is not
* supported. NuttX does not support default signal actions.
*
* argv - argv[] is the argument list for the new task. argv[] is an
* array of pointers to null-terminated strings. The list is terminated
* with a null pointer. The value in argv[0] should point to a filename
* that is associated with the process image being started by the
* posix_spawn() or posix_spawnp() functions.
*
* envp - The envp[] argument is not used by NuttX and may be NULL. In
* standard implementations, envp[] is an array of character pointers to
* null-terminated strings that provide the environment for the new
* process image. The environment array is terminated by a null pointer.
* In NuttX, the envp[] argument is ignored and the new task will simply
* inherit the environment of the parent task.
*
* Returned Value:
* posix_spawn() and posix_spawnp() will return zero on success.
* Otherwise, an error number will be returned as the function return
* value to indicate the error:
*
* - EINVAL: The value specified by 'file_actions' or 'attr' is invalid.
* - Any errors that might have been return if vfork() and excec[l|v]()
* had been called.
*
* Assumptions/Limitations:
* - NuttX provides only posix_spawn() or posix_spawnp() behavior
* depending upon the setting of CONFIG_BINFMT_EXEPATH: If
* CONFIG_BINFMT_EXEPATH is defined, then only posix_spawnp() behavior
* is supported; otherwise, only posix_spawn behavior is supported.
* - The 'envp' argument is not used and the 'environ' variable is not
* altered (NuttX does not support the 'environ' variable.
* - Process groups are not supported (POSIX_SPAWN_SETPGROUP).
* - Effective user IDs are not supported (POSIX_SPAWN_RESETIDS).
* - Signal masks and signal default actions cannot be modified in the
* newly executed task (POSIX_SPAWN_SETSIGDEF and POSIX_SPAWN_SETSIGMASK).
*
* POSIX Compatibility
* - The value of the argv[0] received by the child task is assigned by
* NuttX. For the caller of posix_spawn(), the provided argv[0] will
* correspond to argv[1] received by the new task.
