This group discusses the functions to handle files and directories.
These functions make it easier to do a number of file and directory operations such as getting the list of files in a directory, splitting paths, and finding out file size and type.
- Warning:
- All functions in this group are blocking, which means they may take a long time to return; use them carefully.
See an example here.

void eina_file_close | ( | Eina_File * | file | ) |
Unrefs the file handler.
This decrements the file's reference count and if it reaches zero it closes the file.
- Parameters:
-
[in] file The file handler to unref

- 1.1
- Since :
- 3.0
void eina_file_close_from | ( | int | fd, |
int * | except_fd | ||
) |
Close all file descriptors that are open at or above the given fd.
This closes all open file descriptors that are equal to or of higher value than the given inpit fd given. This is intended for niche use like closing all open files just before exec()ing a new process after calling fork(). The except_fd array can be NULL if no fd's are to be skipped, but if some fd's are to skip being closed then this will be an array of fd numbers being terminated by a fd value of -1.
- Parameters:
-
[in] fd The fd value to begin closing at [in] except_fd An array of fd's not to close terminated by -1 as the last invalid fd
- Since (EFL) :
- 1.24
Eina_Bool eina_file_copy | ( | const char * | src, |
const char * | dst, | ||
Eina_File_Copy_Flags | flags, | ||
Eina_File_Copy_Progress | cb, | ||
const void * | cb_data | ||
) |
Copies one file to another using the fastest possible way and report progress.
This function tries to splice if it is available. It is blocked until the whole file is copied or it fails.
- Parameters:
-
[in] src The source file. [in] dst The destination file. [in] flags Controls what is copied (data is always copied). [in] cb If it is provided will be called with file copy progress information. [in] cb_data Context data to provide to cb
during copy.
- Returns:
- EINA_TRUE on success, EINA_FALSE otherwise (and
dst
will be deleted)
- Note:
- During the progress it may call back
cb
with the progress summary.
- Since :
- 3.0
Eina_Bool eina_file_dir_list | ( | const char * | dir, |
Eina_Bool | recursive, | ||
Eina_File_Dir_List_Cb | cb, | ||
void * | data | ||
) |
Lists all the files on the directory by calling the function for every file found.
This function calls cb
for each file that is in dir
. To have cb
called on the files that are in subdirectories of dir
, recursive
should be EINA_TRUE. In other words, if recursive
is EINA_FALSE, only direct children of dir
are operated on, if recursive
is EINA_TRUE the entire tree of files that is below dir
is operated on.
If cb
or dir
is NULL
or if dir
is a string of size 0, or if dir
cannot be opened, this function returns EINA_FALSE immediately. Otherwise, it returns EINA_TRUE.
- Parameters:
-
[in] dir The directory name [in] recursive Iterate recursively in the directory [in] cb The callback to be called [in] data The data to pass to the callback
- Returns:
- EINA_TRUE on success, otherwise EINA_FALSE
- Since :
- 3.0
- Examples:
- eina_file_01.c.
Eina_Iterator* eina_file_direct_ls | ( | const char * | dir | ) |
Gets an iterator to list the content of a directory, with direct information.
This returns an iterator for Eina_File_Direct_Info, the name of each file in dir
is only fetched when advancing the iterator, which means there is cost associated with creating the list and stopping halfway through it.
- Parameters:
-
[in] dir The name of the directory to list
- Returns:
- An Eina_Iterator that walks over the files and directories in
dir
. On failure, it returnsNULL
.
- Warning:
- If readdir_r doesn't contain file type information, file type is EINA_FILE_UNKNOWN.
- The Eina_File_Direct_Info returned by the iterator must not be modified in any way.
- When the iterator is advanced or deleted the Eina_File_Direct_Info returned is no longer valid.
- Note:
- The container for the iterator is of type DIR*.
- The iterator walks over '.' and '..' without returning them.
- The difference between this function and eina_file_stat_ls() is that it may not get the file type information however it is likely to be faster.
- See also:
- eina_file_ls()
- Since :
- 3.0
- Examples:
- eina_file_01.c.
Eina_File* eina_file_dup | ( | const Eina_File * | file | ) |

- The stringshared filename of the file
- Since (EFL) :
- 1.1
- Since :
- 3.0
Eina_Iterator* eina_file_ls | ( | const char * | dir | ) |
Gets an iterator to list the content of a directory.
This returns an iterator for shared strings, the name of each file in dir
is only fetched when advancing the iterator, which means there is very little cost associated with creating the list and stopping halfway through it.
- Parameters:
-
[in] dir The name of the directory to list
- Returns:
- An Eina_Iterator that walks over the files and directories in
dir
. On failure, it returnsNULL
.
- Note:
- The iterator hands the user a stringshared value with the full path. The user must free the string using eina_stringshare_del() on it.
- The container for the iterator is of type DIR*.
- The iterator walks over '.' and '..' without returning them.
- See also:
- eina_file_direct_ls()
- Since :
- 3.0

is set appropriately.
- Note:
- If the
templatename
is a simple directory name (no relative or absolute path to another directory), then a temporary directory will be created inside the system temporary directory (
- See also:
- eina_environment_tmp_get()). If the
templatename
contains a directory separator ('/', or '\' on Windows) then the temporary directory will be created inside that other directory, which must exist and be writeable. (since 1.17) - eina_file_mkstemp()

If the
templatename
is a simple file name (no relative or absolute path to another directory), then a temporary file will be created inside the system temporary directory (
- See also:
- eina_environment_tmp_get()). If the
templatename
contains a directory separator ('/', or '\' on Windows) then the file will be created inside this directory, which must exist and be writeable. Use ./filename.XXXXXX to create files in the current working directory. (since 1.17) - eina_file_mkdtemp()

Eina_Bool eina_file_unlink | ( | const char * | pathname | ) |
Unlinks file.
This function is a wrapper around the unlink() system call. It removes a link to a file.
- Parameters:
-
[in] pathname File name to unlink.

Eina_Bool eina_file_virtual | ( | Eina_File * | file | ) |
Tells if a file is a real file or only exists in memory.
- Parameters:
-
[in] file The file to test
- Returns:
- EINA_TRUE if the file is a virtual file
- Since (EFL) :
- 1.8

- 3.0
Eina_File* eina_file_virtualize | ( | const char * | virtual_name, |
const void * | data, | ||
unsigned long long | length, | ||
Eina_Bool | copy | ||
) |
Creates a virtual file from a memory pointer.
- Parameters:
-
[in] virtual_name A virtual name for Eina_File, if NULL
, a generated one will be given[in] data The memory pointer to take data from [in] length The length of the data in memory [in] copy EINA_TRUE if the data must be copied
- Returns:
- Eina_File handle to the file

Eina_Iterator* eina_file_xattr_get | ( | Eina_File * | file | ) |
Gets the extended attribute of an open file.
- Parameters:
-
[in] file The file handler to request the extended attribute from
- Returns:
- An iterator
- Note:
- The iterator lists all the extended attribute names without allocating them, so you need to copy them yourself if needed.
