vxworks file attribute

[Alex Tang]

hi :
is there any vxworks file attribute for a file that allows it to be
accessed (read or wroten )by only one task/process at a time ? For
example ,while task A is reading file abc.txt , if task B want to read
it , OS will delay task access abc.txt

thank you!

regards
Alex

VxWorks does not support POSIX file locking operations so any mutual
exclusion on file access has to be implemented at the application
level.
