Initializes the Ecore_File library.

Returns
  `1` or greater on success, otherwise `0` on error.

This function sets up Ecore_File and the services it will use (monitoring, downloading, PATH related feature). It returns 0 on failure, otherwise it returns the number of times it has already been called.

Gets the monitored path.

Parameters

  em | The Ecore_File_Monitor to query.

Returns
  The path that is monitored by `em`.

This function returns the monitored path that has been monitored by ecore_file_monitor_add(). `em` must be the value returned by ecore_file_monitor_add(). If `em` is `NULL`, the function returns `NULL`.

## ◆ ecore_file_path_dir_exists()

EAPI Eina_Bool ecore_file_path_dir_exists | ( | const char * | in_dir | ) |

Checks if the given directory is in PATH.

Parameters

  in_dir | The name of the directory to search in PATH.

Returns
  `EINA_TRUE` if the directory exist in PATH, `EINA_FALSE` otherwise.

This function checks if `in_dir` is in the environment variable PATH. If `in_dir` is `NULL`, or if PATH is empty, or `in_dir` is not in PATH, the function returns `EINA_FALSE`, otherwise it returns `EINA_TRUE`.

References EINA_FALSE, EINA_LIST_FOREACH, and EINA_TRUE.

## ◆ ecore_file_app_installed()

EAPI Eina_Bool ecore_file_app_installed | ( | const char * | exe | ) |

Checks if the given application is installed.

Parameters

  exe | The name of the application

Returns
  `EINA_TRUE` if the `exe` is in PATH and is executable, `EINA_FALSE` otherwise.

This function checks if `exe` exists in PATH and is executable. If `exe` is `NULL` or is not executable, the function returns `EINA_FALSE`, otherwise it returns `EINA_TRUE`.

References ecore_file_can_exec(), EINA_FALSE, EINA_LIST_FOREACH, and EINA_TRUE.

## ◆ ecore_file_app_list()

EAPI Eina_List * ecore_file_app_list | ( | void |  | ) |

Gets a list of all the applications installed on the system.

Returns
  An Eina_List containing all the executable files in the system.

This function returns a list of allocated strings of all the executable files. If no files are found, the function returns `NULL`. When not needed anymore, the element of the list must be freed.

## ◆ ecore_file_download()

EAPI Eina_Bool ecore_file_download | ( | const char * | url,
|  | const char * | dst,
|  | Ecore_File_Download_Completion_Cb | completion_cb,
|  | Ecore_File_Download_Progress_Cb | progress_cb,
|  | void * | data,
|  | Ecore_File_Download_Job ** | job_ret
| ) |  |

Downloads the given url to the given destination.

Parameters

  url | The complete url to download.
  dst | The local file to save the downloaded to.
  completion_cb | A callback called on download complete.
  progress_cb | A callback called during the download operation.
  data | User data passed to both callbacks.
  job_ret | Job used to abort the download.

Returns
  `EINA_TRUE` if the download start or `EINA_FALSE` on failure.

This function starts the download of the URL `url` and saves it to `dst`. `url` must provide the protocol, including 'http://', 'ftp://' or 'file://'. Ecore_File must be compiled with CURL to download using http and ftp protocols. If `dst` is ill-formed, or if it already exists, the function returns `EINA_FALSE`. When the download is complete, the callback `completion_cb` is called and `data` is passed to it. The `status` parameter of `completion_cb` will be filled with the status of the download (200, 404,...). The `progress_cb` is called during the download operation, each time a packet is received or when CURL wants. It can be used to display the percentage of the downloaded file. Return 0 from this callback, if provided, to continue the operation or anything else to abort the download. The only operations that can be aborted are those with protocol 'http' or 'ftp'. In that case `job_ret` can be passed to ecore_file_download_abort() to abort that download job. Similarly ecore_file_download_abort_all() can be used to abort all download operations. This function returns `EINA_TRUE` if the download starts, `EINA_FALSE` otherwise.

## ◆ ecore_file_download_full()

EAPI Eina_Bool ecore_file_download_full | ( | const char * | url,
|  | const char * | dst,
|  | Ecore_File_Download_Completion_Cb | completion_cb,
|  | Ecore_File_Download_Progress_Cb | progress_cb,
|  | void * | data,
|  | Ecore_File_Download_Job ** | job_ret,
|  | Eina_Hash * | headers
| ) |  |

Downloads the given url to the given destination with additional headers.

Parameters

  url | The complete url to download.
  dst | The local file to save the downloaded to.
  completion_cb | A callback called on download complete.
  progress_cb | A callback called during the download operation.
  data | User data passed to both callbacks.
  job_ret | Job used to abort the download.
  headers | pointer of header lists.

Returns
  `EINA_TRUE` if the download start or `EINA_FALSE` on failure.

## ◆ ecore_file_download_abort_all()

EAPI void ecore_file_download_abort_all | ( | void |  | ) |

Aborts all downloads.

This function aborts all the downloads that have been started by ecore_file_download(). It loops over the started downloads and call ecore_file_download_abort() for each of them. To abort only one specific download operation, call ecore_file_download_abort().

References ecore_file_download_abort(), and EINA_LIST_FREE.

## ◆ ecore_file_download_abort()

EAPI void ecore_file_download_abort | ( | Ecore_File_Download_Job * | job | ) |

Aborts the given download job and call the completion_cb callback with a status of 1 (error).

Parameters

  job | The download job to abort.

This function aborts a download operation started by ecore_file_download(). `job` is the Ecore_File_Download_Job structure filled by ecore_file_download(). If it is `NULL`, this function does nothing. To abort all the currently downloading operations, call ecore_file_download_abort_all().

## ◆ ecore_file_download_protocol_available()

EAPI Eina_Bool ecore_file_download_protocol_available | ( | const char * | protocol | ) |

Checks if the given protocol is available.

Parameters

  protocol | The protocol to check.

Returns
  `EINA_TRUE` if protocol is handled, `EINA_FALSE` otherwise.

This function returns `EINA_TRUE` if `protocol` is supported, `EINA_FALSE` otherwise. `protocol` can be 'http://', 'ftp://' or 'file://'. Ecore_FILE must be compiled with CURL to handle http and ftp protocols.
