I'm currently trying to wrap some windows methods in a nice object, but
I have trouble with strings.
basically, this is what i do (slightly shortened:)
cdef extern from "mmsystem.h":
ctypedef struct MIDIINCAPS:
int wMid # manufacturer ID
int wPid # product ID
int vDriverVersion # version of the driver
char szPname[32] # product name (NULL terminated string)
MMRESULT midiInGetDevCaps(UINT uDeviceID, MIDIINCAPS *mic, UINT cbmic)
cdef class outPort:
cdef public int port
cdef public int manufacturer_int # manufacturer ID
cdef public int product_int # product ID
cdef public int driver_version_int # version of the driver
def getPortInfo(self):
cdef MIDIINCAPS mic
midiInGetDevCaps(self.port, &mic, sizeof(MIDIINCAPS))
self.manufacturer_int = mic.wMid
self.product_int = mic.wPid
self.driver_version_int = mic.vDriverVersion
Now, this is all fine. But how do I get that pesky char szPname[32] into
a python accessible string attribute? Nothing I tried would both compile
and return the string in question when accesed from python...
trust me: more questions woll follow. the documentation is fine by
normal python standards, meaning it's still slightly lacking.. :-)
