# zx_debuglog_create

## Summary

Create an object allowing access to the kernel debuglog.

## Declaration

```c
#include <zircon/syscalls.h>

zx_status_t zx_debuglog_create(zx_handle_t resource,
                               uint32_t options,
                               zx_handle_t* out);
```

## Description

`zx_debuglog_create()` creates an object allowing access to the kernel
debuglog using the `zx_debuglog_read()` and `zx_debuglog_write()` syscalls.

If *options* is set to `0`, the returned handle will have the
**ZX_RIGHT_WRITE** right, giving write-only access to the kernel debuglog. If
*options* is set to **ZX_LOG_FLAG_READABLE**, the returned handle will
additionally have **ZX_RIGHT_READ**, giving read/write access to the kernel
debuglog.

## Rights

*resource* must have resource kind **ZX_RSRC_KIND_ROOT**.

## Return value

`zx_debuglog_create()` returns **ZX_OK** on success, returning a handle to the
created object in *out*.

In the event of failure, a negative error value is returned.

## Errors

**ZX_ERR_INVALID_ARGS**  *options* contained a value not understood by the kernel

**ZX_ERR_WRONG_TYPE**  *resource* was not of the kind **ZX_RSRC_KIND_ROOT**.

**ZX_ERR_NO_MEMORY**  Failure due to lack of memory.
