or the interface may not be implemented on Linux.
Имя (Name)
setpgrp — set the process group ID
Синопсис (Synopsis)
#include <unistd.h>
pid_t setpgrp(void);
Описание (Description)
If the calling process is not already a session leader, setpgrp()
sets the process group ID of the calling process to the process
ID of the calling process. If setpgrp() creates a new session,
then the new session has no controlling terminal.
The setpgrp() function has no effect when the calling process is
a session leader.
Возвращаемое значение (Return value)
Upon completion, setpgrp() shall return the process group ID.

The following sections are informative.
Примеры (Examples)
None.
Использование в приложениях (Application usage)
It is unspecified whether this function behaves as setpgid(0,0)
or setsid() unless the process is already a session leader.
Therefore, applications are encouraged to use setpgid() or
setsid() as appropriate.
Обоснование (Rationale)
None.
Будущие направления (Future directions)
The setpgrp() function may be removed in a future version.
