ARGUMENTS
display
Specifies the connection to the X server.
list
Specifies a list of null-terminated character strings.
count
Specifies the number of strings specified.
style
Specifies the manner in which the property is encoded.
text_prop_return
Returns the
structure.
text_prop
Specifies the
structure to be used.
list_return
Returns a list of null-terminated character strings.
count_return
Returns the number of .
list
Specifies the list of strings to be freed.
DESCRIPTION
The
and
functions set the specified
value to a set of null-separated elements representing the concatenation
of the specified list of null-terminated text strings. The input text
strings must be given in the current locale encoding (for
and
or in UTF-8 encoding (for
The functions set the encoding field of text_prop_return to an
for the specified display
naming the encoding determined by the specified style
and convert the specified text list to this encoding for storage in
the text_prop_return value field.
If the style
or
is specified,
this encoding is ``STRING'' or ``COMPOUND_TEXT'', respectively.
If the style
is specified,
this encoding is ``UTF8_STRING''.
(This is an extension introduced by The XFree86 Project, Inc. in their 4.0.2
release. Its presence is indicated by the macro
If the style
is specified,
this encoding is the encoding of the current locale.
If the style
is specified,
this encoding is ``STRING'' if the text is fully convertible to STRING,
else ``COMPOUND_TEXT''.
A final terminating null byte is stored at the end of the value field
of text_prop_return but is not included in the nitems member.
If insufficient memory is available for the new value string,
the functions return
If the current locale is not supported,
the functions return
In both of these error cases,
the functions do not set text_prop_return.
To determine if the functions are guaranteed not to return
use
If the supplied text is not fully convertible to the specified encoding,
the functions return the number of unconvertible characters.
Each unconvertible character is converted to an implementation-defined and
encoding-specific default string.
Otherwise, the functions return
Note that full convertibility to all styles except
is guaranteed.
To free the storage for the value field, use
The
and
functions return a list of text strings representing the
null-separated elements of the specified
structure. The returned strings are encoded using the current locale encoding
(for
and
or in UTF-8 (for
The data in text_prop must be format 8.
Multiple elements of the property (for example, the strings in a disjoint
text selection) are separated by a null byte.
The contents of the property are not required to be null-terminated;
any terminating null should not be included in text_prop.nitems.
If insufficient memory is available for the list and its elements,
and
return
If the current locale is not supported,
the functions return
Otherwise, if the encoding field of text_prop is not convertible
to the encoding of the current locale,
the functions return
For supported locales,
existence of a converter from COMPOUND_TEXT, STRING, UTF8_STRING
or the encoding of the current locale is guaranteed if
returns
for the current locale (but the actual text
may contain unconvertible characters).
Conversion of other encodings is implementation-dependent.
In all of these error cases,
the functions do not set any return values.
Otherwise,
and
return the list of null-terminated text strings to list_return
and the number of text strings to count_return.
If the value field of text_prop is not fully convertible to the
encoding of the current locale,
the functions return the number of unconvertible characters.
Each unconvertible character is converted to a string in the
current locale that is specific to the current locale.
To obtain the value of this string,

It may be freed after the current locale is changed.
