## Function Documentation

## ◆ evas_cserve_path_get()

const char* evas_cserve_path_get | ( | void |  | ) |

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

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.
