FwupdPlugin.size_from_uint64
Description: Reference for FwupdPlugin.size_from_uint64

### Function

# FwupdPluginsize_from_uint64

since: 2.1.2

#### Declaration [src]

    gboolean
    fu_size_from_uint64 (
      guint64 value,
      gsize* out,
      GError** error
    )

#### Description [src]

Safely converts a 64-bit unsigned integer to a #gsize value, ensuring the value fits within the platform’s #gsize range. On 32-bit platforms where #gsize is 32 bits, this prevents silent truncation that could lead to security vulnerabilities.

Available since: 2.1.2

#### Parameters

`value`

  Type: `guint64`

  A 64-bit unsigned integer.

`out`

  Type: `gsize*`

  Output location for the converted value.

  The argument will be set by the function.

`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: `gboolean`

`TRUE` if the conversion was successful, `FALSE` if the value exceeds #G_MAXSIZE.
