add-library-path clj

(add-library-path libname pathtype path)

Add a search path. The multimethod (base/find-library pathtype path) is called to expand the pathtype, path into one or more actual paths to attempt. Valid existing pathtypes are

:system - no changes, looks in system paths. :java-library-path - Appends library to all paths in java-library-paths :resource - Uses jna Native/extractFromResourcePath

as-ptr clj

(as-ptr item)

c-library-name clj

(c-library-name)

char-ptr-ptr->string-vec clj

(char-ptr-ptr->string-vec num-strings char-ptr-ptr)

Decode a char** ptr.

checknil clj

(checknil value)

clear-library-paths clj

(clear-library-paths libname)

Clear the library search paths for a specific library. Use with care; the default if non found is: [[:system libname] [:java-library-path libname]].

create-ptr-ptr clj

(create-ptr-ptr ptr)

Create a pointer to a pointer.

def-jna-fn clj macro

(def-jna-fn libname fn-name docstring rettype & argpairs)

Define a dynamically bound fn. Upon first call, it will attempt to find the function pointer from libname. Argpair is of type [symbol type-coersion], symbol cannot match type-coersion.

malloc clj

(malloc num-bytes)

Malloc a pointer of Y bytes. Track using both resource context and gc system.

malloc-untracked clj

(malloc-untracked num-bytes)

Malloc pointer of Y bytes. Up to call to call Native/free on result at some point
