Function Documentation

l4_debugger_query_obj_infos()

l4_msgtag_t l4_debugger_query_obj_infos ( l4_cap_idx_t  cap, l4_addr_t  ku_mem_addr, l4_size_t  ku_mem_size, l4_umword_t  skip, l4_umword_t *  result_cnt, l4_umword_t *  result_all  )

inline

Retrieve information from the kernel about all objects in the mapping database and write data to the passed KU memory.

Parameters

	cap	Capability of the debugger object.
	ku_mem_addr	Address of the KU memory for writing the information.
	ku_mem_size	Size of the KU memory to writing the information.
	skip	Number of objects to skip.
[out]	result_cnt	Number of objects in the mapping database.
[out]	result_all	Number of objects written to the KU memory.

Note

The kernel will only write a number of object information which fits to the passed KU memory. To retrieve missing object information, repeat the call and adapt the skip parameter accordingly.

If this system call is performed several times, the number of kernel objects might have changed in the meantime.
