User ID and Group ID
If the set-user-ID mode bit (S_ISUID) of the new process image file is set (see the chmod(2)
reference page), the effective user ID of the new process image is set to the user ID of the owner
of the new process image file. Similarly, if the set-group-ID mode bit (S_ISGID) of the new pro-
cess image file is set, the effective group ID of the new process image is set to the group ID of the
new process image file. The real user ID, real group ID, and supplementary group IDs of the new
process image remain the same as those of the calling process image. The effective user ID and
effective group ID of the new process image are saved (as the saved-set user ID and the saved-set
group ID) for use by the setuid() function.
OSS Attributes
These OSS attributes of the calling process image are unchanged after successful completion of
the tdm_execvep() function:
• OSS process ID (PID)
• Parent OSS process ID
• Process group ID
• Session membership
• Real user ID
• Real group ID
• Supplementary group IDs
• The time left until an alarm clock signal is posted (see the alarm(3) reference page)
