Name
cyg_bundle_read — Extract data from a bundle item
Synopsis
#include <cyg/bundle/bundle_api.h>
uint32_t cyg_bundle_read(cyg_bundle_object_t *ic, void *dst, uint32_t offset, uint32_t amount);
Description
This function copies a chunk of data from the reference bundle
object to the supplied dst address.
The offset parameter is the
byte-offset within the data object where reading should start, with
the amount specifying the number of bytes to be
read. If the data is held in a compressed format then it will be automatically
decompressed before being written to the supplied
dst address. In this case the
offset parameter always refers to the
offset within the decompressed data.
Return value
Number of bytes read, or 0 on error. The returned number of bytes read
may be less than the specified amount if an
attempt is made to read more data than is available for the referenced
object.
