linradio toolkit - Information for developers

The driver in linradio-toolkit can be compiled either as a user-mode library or as a loadable linux kernel module. Both versions can be used transparently through liblinradio.so and wrapi.h.

User-mode driver:

Portable and easy to install (does not depend on kernel version)
Requires root privileges for ISA cards
Requires explicit save/restore of receiver state
Detecting and initializing the receiver takes several seconds
Low-level code in liblinradio.so (header: wrapi.h)

Loadable module:

Persistent driver state
No initialization delay
Applications don't need root privileges
Mutual exclusion
Low-level code in linradio.o (kernel module)
ioctl-based access through /dev/winradio*
liblibradio.so transparently maps C function calls to ioctls
Same API as the user-mode driver (wrapi.h)
