No, it does not. PCRE has its own API. There is a POSIX wrapper that
allows applications to call PCRE via a POSIX API, but this does not
provide all the functionality of PCRE.

I think perhaps you are asking for what system calls PCRE uses
internally. There is no list of these, but the PCRE C library should use
only functions that are defined as part of the C standard. PCRE should
work on any system that has a standard C compiler and a standard C
library. See the NON-AUTOTOOLS-BUILD file in the PCRE distribution.
