Description

Functions

xfce_utf8_remove_controls ()

gchar *
xfce_utf8_remove_controls (gchar *str,
                           gssize max_len,
                           const gchar *end);

Removes all control characters from str up to end or up to max_len characters (note that characters does not mean bytes with UTF-8), where both str and max_len may not be given.

Control characters are replaced in str by whitespaces, no new string will be allocated. The operation is done in-place.

Parameters

str	target string.
max_len	max characters to check or -1 for no character limit.
end	pointer to the endpoint in `str` or `NULL` for no endpoint.

Returns

pointer to str or NULL on error.

xfce_utf8_strndup ()

gchar *
xfce_utf8_strndup (const gchar *src,
                   gssize max_len);

Duplicates the src string up to max_len characters (note that characters does not mean bytes with UTF-8).

The caller is responsible to free the returned string using g_free() when no longer needed.

Parameters

src	target string.
max_len	max characters to duplicate or -1 for no character limit.

Returns

pointer to the newly allocated string.
