Function Documentation

◆ evas_cserve_path_get()

EINA_DEPRECATED const char* evas_cserve_path_get ( void )

Deprecated:: This function now returns NULL as cserve2 support has been removed

Get the path for the cserve binary to execute

There is little need for anyone except a desktop environment to call this. This can be called before evas_init() has been called. It will try and find the full path to the to the cserve binary to run to provide cserve image and font caching services for evas.

Returns: NULL if error, or a string with the full path to the cserve binary.

Since: 1.8

◆ evas_cserve_image_cache_contents_clean()

void evas_cserve_image_cache_contents_clean ( Evas_Cserve_Image_Cache * cache )

Completely discard/clean a given images cache, thus re-setting it.

Parameters

cache A handle to the given images cache.

◆ evas_font_data_cache_set()

void evas_font_data_cache_set	(	Evas_Font_Data_Cache	options,
		int	byte
	)

Set the limit in bytes for memory allocated by font glyphs in evas.

Parameters

[in]	options	for caching.
[in]	bytes	cache size in bytes, pass negative value to ignore the limit.

Since: 1.24

References EVAS_FONT_DATA_CACHE_TEXTURE.

◆ evas_font_data_cache_get()

int evas_font_data_cache_get ( Evas_Font_Data_Cache options )

Get the limit in bytes for memory allocated by font glyphs in evas.

Parameters

[in] options for caching.

Returns: Returns font allocated memory cache limit, if value is negative this means no limit.

Since: 1.24
