+==========
+
+library that provide some missing posix threading function to the bionic libc.
+
+while i was porting tens of linux projects under the dSploit android app i found that
+the bionic libc does not provide some POSIX thread functions like `pthread_cancel`, `pthread_testcancel` and so on.
+
+so, i developed this library, which exploit some unused bits in the bionic thread structure.
+
+there is many thing to develop, like support for deferred cancels, but basic thread cancellation works :smiley:
+
+i hope that you find this library useful :wink:
