I'm trying to use cl_fmap_open_handle and the callback, however I'm finding the comments on this somewhat confusing and need clarifying:
/** * @brief Read callback function type. * * A callback function pointer type for reading data from a cl_fmap_t that uses * reads data from a handle interface. * * Read 'count' bytes starting at 'offset' into the buffer 'buf' * * Thread safety: It is guaranteed that only one callback is executing for a * specific handle at any time, but there might be multiple callbacks executing * for different handle at the same time. * * @param handle The handle passed to cl_fmap_open_handle, its meaning is up * to the callback's implementation * @param buf A buffer to read data into, must be at least offset + count * bytes in size. * @param count The number of bytes to read. * @param offset The the offset into buf to read the data to. If successful, * the number of bytes actually read is returned. Upon reading * end-of-file, zero is returned. Otherwise, a -1 is returned * and the global variable errno is set to indicate the error. */ typedef off_t (*clcb_pread)(void *handle, void *buf, size_t count, off_t offset); First it says - Read 'count' bytes starting at 'offset' into the buffer 'buf' Then it says - @param offset The the offset into buf to read the data to. So which is it, is offset the offset within the file or the buffer? * Lloyd _______________________________________________ clamav-devel mailing list clamav-devel@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-devel Please submit your patches to our Github: https://github.com/Cisco-Talos/clamav-devel/pulls Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
