Open System Services System Calls Reference Manual (G06.25+, H06.03+)

fstat(2) OSS System Calls Reference Manual
from the inode for the socket are returned for the
permission bits. The access flags are also
returned from the inode.
S_IRWXG Group class
S_IRWXO Other class
S_IRWXU Owner class
S_ISGID Set group ID on execution
S_ISUID Set user ID on execution
S_ISVTX Sticky bit; used only for directories (not ORed for files in /G, the
Guardian file system)
S_NONSTOP Regular file in the OSS file system protected by disk process
checkpointing. (Files in /G cannot have this bit set.)
When set, indicates that return from a write operation does not
occur until both the primary and backup disk processes have the
data (thereby protecting the data against a single point of
failure).
OSS file-system data caching is disabled for write operations on
files for which this bit is set. Performance is slower than when
caching is used, but data integrity protection increases. Perfor-
mance is faster than when the O_SYNC bit in the open() func-
tion oflag parameter is used, but data integrity protection is less
than that provided by O_SYNC use.
S_TRUST Indicates that the file does not contain code for an uncooperative |
process or code to examine or modify I/O buffers. This flag |
suppresses operating system protection of the buffers when the |
memory segment containing the buffers is not shared. This flag |
applies only to loadfiles for a process and can be set only by a |
user with appropriate privileges (the super ID).
S_TRUSTSHARED
Indicates that the file does not contain code for an uncooperative |
process or code to examine or modify I/O buffers. This flag |
suppresses operating system protection of the buffers regardless |
of whether the memory segment containing the buffers is shared. |
This flag applies only to loadfiles for a process and can be set |
only by a user with appropriate privileges (the super ID).
