[pcre-dev] about the posix API depend by PCRE

Hi,


I want to port PCRE to one private OS.
I know PCRE depend on posix APIs.
However, my private OS doesn't support POSIX. I plan to implement a posix layer on my system.


So, Could you please tell me where can I find the list of posix APIs been depended by PCRE?
Then I can only care about them instead of whole posix.


Thanks
