Re: Including STRTOK_R in a LSM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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.

I am aware strtok was removed from the kernel in 2002. However strtok_r is more
desirable than strsep as I do not want to know about 'blank fields' (2
consecutive delimiters). Is it acceptable to simply include the strtok_r code
in my security module? or should I create a wrapper for strsep to ignore
blanks?

                printf("\"%s\"\n", p);
}

"bar"


q.e.d.
