gMountGuessContentTypeSync {RGtk2} | R Documentation

## gMountGuessContentTypeSync

### Description

Tries to guess the type of content stored on `mount`. Returns one or more textual identifiers of well-known content types (typically prefixed with "x-content/"), e.g. x-content/image-dcf for camera memory cards. See the shared-mime-info (http://www.freedesktop.org/wiki/Specifications/shared-mime-info-spec) specification for more on x-content types.

### Usage

    gMountGuessContentTypeSync(object, force.rescan, cancellable = NULL,
        .errwarn = TRUE)

### Arguments

``object`` | a `GMount`
``force.rescan`` | Whether to force a rescan of the content. Otherwise a cached result will be used if available
``cancellable`` | optional `GCancellable` object, `NULL` to ignore
`.errwarn` | Whether to issue a warning on error or fail silently

### Details

This is an synchronous operation and as such may block doing IO; see `gMountGuessContentType` for the asynchronous version. Since 2.18

### Value

A list containing the following elements:

`retval` | [character] a list of content types or `NULL` on error.
``error`` | a `GError` location to store the error occuring, or `NULL` to ignore
