| |
What I need is to ignore double delimiters such as (::). This can be done trivially with a string comparison to check for "\0". What I want to know is if it is ok to include the strtok_r code in my security module, or if strtok was removed for a very good reason. I am porting a lot of existing code which already uses strtok_r to a kernel security module.
Thanks,
Cliffe.
