Return values
If the system call succeeds the return value is 0.
If the system call fails the return value is one of the following errno values:
-EACCES |
An attempt was made to change the process group ID of one of the children of the calling process and the child had already performed an sys_execve. |
-EINVAL |
ecx is less than 0. |
-EPERM |
An attempt was made to move a process into a process group in a different session, or to change the process group ID of one of the children of the calling process and the child was in a different session, or to change the process group ID of a session leader. |
-ESRCH |
ebx is not the current process and not a child of the current process. |

Remarks
A child created via sys_fork inherits its parent's process group ID. The process group ID is preserved across an sys_execve .
