                 GError **error);

ev_mkdtemp ()

gchar *

ev_xfer_uri_simple ()

gboolean
ev_xfer_uri_simple (const char *from,
                    const char *to,
                    GError **error);

Performs a g_file_copy() from from to to .

Parameters

from

the source URI

 

to

the target URI

 

error

a GError location to store an error, or NULL

 

Returns

TRUE on success, or FALSE on error with error filled in


ev_file_copy_metadata ()

gboolean
ev_file_copy_metadata (const char *from,
                       const char *to,
                       GError **error);

Since: 3.4


ev_file_get_mime_type ()

gchar *
ev_file_get_mime_type (const gchar *uri,
                       gboolean fast,
                       GError **error);

Parameters

uri

the URI

 

fast

whether to use fast MIME type detection

 

error

a GError location to store an error, or NULL

 

Returns

a newly allocated string with the MIME type of the file at uri , or NULL on error or if the MIME type could not be determined


ev_file_uncompress ()

gchar *
ev_file_uncompress (const gchar *uri,
                    EvCompressionType type,
                    GError **error);

Uncompresses the file at uri .

If type is EV_COMPRESSION_NONE, it does nothing and returns NULL.

Otherwise, it returns the filename of a temporary file containing the decompressed data from the file at uri . On error it returns NULL and fills in error .

It is the caller's responsibility to unlink the temp file after use.

Parameters

uri

a file URI

 

type

the compression type

 

error

a GError location to store an error, or NULL

 

Returns

a newly allocated string URI, or NULL on error


ev_file_compress ()

gchar *
ev_file_compress (const gchar *uri,
                  EvCompressionType type,
                  GError **error);

Compresses the file at uri .

If type is EV_COMPRESSION_NONE, it does nothing and returns NULL.

Otherwise, it returns the filename of a temporary file containing the compressed data from the file at uri .

On error it returns NULL and fills in error .

It is the caller's responsibility to unlink the temp file after use.

Parameters

a file URI

 

type

the compression type

 

error

a GError location to store an error, or NULL

 

Returns

a newly allocated string URI, or NULL on error
