Gio.resources_lookup_data
Description: Reference for Gio.resources_lookup_data

### Function

# Gioresources_lookup_data

since: 2.32

#### Declaration [src]

    GBytes*
    g_resources_lookup_data (
      const char* path,
      GResourceLookupFlags lookup_flags,
      GError** error
    )

#### Description [src]

Looks for a file at the specified `path` in the set of globally registered resources and returns a `GBytes` that lets you directly access the data in memory.

The data is always followed by a zero byte, so you can safely use the data as a C string. However, that byte is not included in the size of the `GBytes`.

For uncompressed resource files this is a pointer directly into the resource bundle, which is typically in some read-only data section in the program binary. For compressed files we allocate memory on the heap and automatically uncompress the data.

`lookup_flags` controls the behaviour of the lookup.

Available since: 2.32

#### Parameters

`path`

  Type: `const char*`

  A path name inside the resource.

  The data is owned by the caller of the function.
  The value is a NUL terminated UTF-8 string.

`lookup_flags`

  Type: `GResourceLookupFlags`

  A `GResourceLookupFlags`.

`error`

  Type: `GError **`

  The return location for a recoverable error.

  The argument can be `NULL`.
  If the return location is not `NULL`, then you must initialize it to a `NULL` `GError*`.
  The argument will be left initialized to `NULL` by the function if there are no errors.
  In case of error, the argument will be set to a newly allocated `GError`; the caller will take ownership of the data, and be responsible for freeing it.

#### Return value

Type: `GBytes`

`GBytes` or `NULL` on error.

The caller of the function takes ownership of the data, and is responsible for freeing it.
