Description

Functions

grl_date_time_from_iso8601 ()

GDateTime *
grl_date_time_from_iso8601 (const gchar *date);

Parameters

date

a date expressed in iso8601 format

GList *
grl_list_from_va (gpointer p,
                  ...);

Returns a GList containing the va_list pointers. Use NULL to finalize them,

[skip]

Parameters

p

first pointer

 

...

va_list pointers

 

Returns

a GList.

grl_paging_translate ()

void
grl_paging_translate (guint skip,
                      guint count,
                      guint max_page_size,
                      guint *page_size,
                      guint *page_number,
                      guint *internal_offset);

Grilo browsing implements a paging mechanism through skip and count values.

But there are some services (like Jamendo or Flickr) where paging is done through a page number and page size: user request all elements in a page, specifying in most cases what is the page size.

This function is a helper for this task, computing from skip and count what is the optimal value of page size (limited by max_page_size ), which page should the user request, and where requested data start inside the page.

By optimal we mean that it computes those values so only one page is required to satisfy the data, using the smallest page size. If user is limiting page size, then more requests to services might be needed. But still page size will be an optimal value.

If page_size is NULL , then page size will be max_page_size . If the later is also 0, then page size will be G_MAXUINT.

Parameters

skip

number of elements to skip

 

count

number of elements to retrieve

 

max_page_size

maximum value for page size (0 for unlimited size)

 

page_size

optimal page size

 

page_number

page which contain the first element to retrieve (starting at 1)

 

internal_offset

in the page_number , offset where first element can be found (starting at 0)
