Declaration

gdouble*
g_key_file_get_double_list (
  GKeyFile* key_file,
  const gchar* group_name,
  const gchar* key,
  gsize* length,
  GError** error
)

Description

Returns the values associated with key under group_name as doubles.

If key cannot be found then NULL is returned and error is set to G_KEY_FILE_ERROR_KEY_NOT_FOUND. Likewise, if the values associated with key cannot be interpreted as doubles then NULL is returned and error is set to G_KEY_FILE_ERROR_INVALID_VALUE.

Available since: 2.12

Parameters

group_name

Type: const gchar*

A group name.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
key

Type: const gchar*

A key.

The data is owned by the caller of the function.
The value is a NUL terminated UTF-8 string.
length

Type: gsize*

The number of doubles returned.

The argument will be set by the function.
error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.
If the return location is not NULL, then you must initialize it to a NULL GError*.
The argument will left initialized to NULL by the method if there are no errors.
In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.

Return value

Type: An array of double

the values associated with the key as a list of doubles, or `NULL` if the
key was not found or could not be parsed. The returned list of doubles
should be freed with `g_free()` when no longer needed.

The length of the array is in the length argument.
The caller of the method takes ownership of the data container, but not the data inside it.
