59 The XmbTextListToTextProperty, XwcTextListToTextProperty and
60 Xutf8TextListToTextProperty functions set the specified XTextProperty
61 value to a set of null-separated elements representing the concatena‐
62 tion of the specified list of null-terminated text strings. The input
63 text strings must be given in the current locale encoding (for Xmb‐
64 TextListToTextProperty and XwcTextListToTextProperty), or in UTF-8
65 encoding (for Xutf8TextListToTextProperty).
66 The functions set the encoding field of text_prop_return to an Atom for
68 the specified display naming the encoding determined by the specified
69 style and convert the specified text list to this encoding for storage
70 in the text_prop_return value field. If the style XStringStyle or
71 XCompoundTextStyle is specified, this encoding is “STRING” or “COM‐
72 POUND_TEXT”, respectively. If the style XUTF8StringStyle is specified,
73 this encoding is “UTF8_STRING”. (This is an extension introduced by
74 The XFree86 Project, Inc., in their 4.0.2 release. Its presence is
75 indicated by the macro X_HAVE_UTF8_STRING.) If the style XTextStyle is
76 specified, this encoding is the encoding of the current locale. If the
77 style XStdICCTextStyle is specified, this encoding is “STRING” if the
78 text is fully convertible to STRING, else “COMPOUND_TEXT”. A final
79 terminating null byte is stored at the end of the value field of
80 text_prop_return but is not included in the nitems member.
81 If insufficient memory is available for the new value string, the func‐
83 tions return XNoMemory. If the current locale is not supported, the
84 functions return XLocaleNotSupported. In both of these error cases,
85 the functions do not set text_prop_return.
86 To determine if the functions are guaranteed not to return XLocaleNot‐
88 Supported, use XSupportsLocale.
89 If the supplied text is not fully convertible to the specified encod‐
91 ing, the functions return the number of unconvertible characters. Each
92 unconvertible character is converted to an implementation-defined and
93 encoding-specific default string. Otherwise, the functions return Suc‐
94 cess. Note that full convertibility to all styles except XStringStyle
95 is guaranteed.
96 To free the storage for the value field, use XFree.
98 The XmbTextPropertyToTextList, XwcTextPropertyToTextList and
100 Xutf8TextPropertyToTextList functions return a list of text strings
101 representing the null-separated elements of the specified XTextProperty
102 structure. The returned strings are encoded using the current locale
103 encoding (for XmbTextPropertyToTextList and XwcTextPropertyToTextList)
104 or in UTF-8 (for Xutf8TextPropertyToTextList). The data in text_prop
105 must be format 8.
106 Multiple elements of the property (for example, the strings in a dis‐
108 joint text selection) are separated by a null byte. The contents of
109 the property are not required to be null-terminated; any terminating
110 null should not be included in text_prop.nitems.
111 If insufficient memory is available for the list and its elements, Xmb‐
113 TextPropertyToTextList, XwcTextPropertyToTextList and Xutf8TextProper‐
114 tyToTextList return XNoMemory. If the current locale is not supported,
115 the functions return XLocaleNotSupported. Otherwise, if the encoding
116 field of text_prop is not convertible to the encoding of the current
117 locale, the functions return XConverterNotFound. For supported
118 locales, existence of a converter from COMPOUND_TEXT, STRING,
119 UTF8_STRING or the encoding of the current locale is guaranteed if
120 XSupportsLocale returns True for the current locale (but the actual
121 text may contain unconvertible characters). Conversion of other encod‐
122 ings is implementation-dependent. In all of these error cases, the
123 functions do not set any return values.
124 Otherwise, XmbTextPropertyToTextList, XwcTextPropertyToTextList and
126 Xutf8TextPropertyToTextList return the list of null-terminated text
127 strings to list_return and the number of text strings to count_return.
128 If the value field of text_prop is not fully convertible to the encod‐
130 ing of the current locale, the functions return the number of uncon‐
131 vertible characters. Each unconvertible character is converted to a
132 string in the current locale that is specific to the current locale.
133 To obtain the value of this string, use XDefaultString. Otherwise,
134 XmbTextPropertyToTextList, XwcTextPropertyToTextList and Xutf8TextProp‐
135 ertyToTextList return Success.
136 To free the storage for the list and its contents returned by Xmb‐
138 TextPropertyToTextList or Xutf8TextPropertyToTextList, use
139 XFreeStringList. To free the storage for the list and its contents
140 returned by XwcTextPropertyToTextList, use XwcFreeStringList.
141 The XwcFreeStringList function frees memory allocated by XwcTextProper‐
143 tyToTextList.
144 The XDefaultString function returns the default string used by Xlib for
146 text conversion (for example, in XmbTextPropertyToTextList). The
147 default string is the string in the current locale that is output when
148 an unconvertible character is found during text conversion. If the
149 string returned by XDefaultString is the empty string (""), no charac‐
150 ter is output in the converted text. XDefaultString does not return
151 NULL.
152 The string returned by XDefaultString is independent of the default
154 string for text drawing; see XCreateFontSet to obtain the default
155 string for an XFontSet.
156 The behavior when an invalid codepoint is supplied to any Xlib function
158 is undefined.
159 The returned string is null-terminated. It is owned by Xlib and should
161 not be modified or freed by the client. It may be freed after the cur‐
162 rent locale is changed. Until freed, it will not be modified by Xlib.
163 The functions Xutf8TextListToTextProperty and Xutf8TextPropertyTo‐
165 TextList are extensions introduced by The XFree86 Project, Inc., in
166 their 4.0.2 release. Their presence is indicated by the macro
167 X_HAVE_UTF8_STRING.

170 The XTextProperty structure contains:
171 typedef struct {
173 unsigned char *value; /* property data */
174 Atom encoding; /* type of property */
175 int format; /* 8, 16, or 32 */
176 unsigned long nitems; /* number of items in value */
177 } XTextProperty;
178 The XICCEncodingStyle structure contains:
180 #define XNoMemory -1
182 #define XLocaleNotSupported -2
183 #define XConverterNotFound -3
184 typedef enum {
185 XStringStyle, /* STRING */
186 XCompoundTextStyle, /* COMPOUND_TEXT */
187 XTextStyle, /* text in owner's encoding (current locale) */
188 XStdICCTextStyle, /* STRING, else COMPOUND_TEXT */
189 XUTF8StringStyle /* UTF8_STRING */
190 } XICCEncodingStyle;
