XmCvtTextPropertyToXmStringTable(library call)							    XmCvtTextPropertyToXmStringTable(library call)

NAME
XmCvtTextPropertyToXmStringTable -- A function that converts from a TextProperty Structure to a StringTable SYNOPSIS
#include <Xm/Xm.h> int XmCvtTextPropertyToXmStringTable (display, text_prop, string_table_return, count_return) Display *display; XTextProperty *text_prop; XmStringTable *string_table_return; int *count_return; (void) DESCRIPTION
XmCvtTextPropertyToXmStringTable converts the specified XTextProperty structure into an XmStringTable, as follows: o If the encoding member of text_prop is the Atom STRING, each returned XmString has a tag of "ISO8859-1" and a text type of XmCHARSET_TEXT. o If the encoding member of text_prop is the encoding of the current locale, and if that encoding is not STRING, each returned XmString has a tag of _MOTIF_DEFAULT_LOCALE and a text type of XmMULTIBYTE_TEXT. o If the encoding member of text_prop is other than STRING or the encoding of the current locale, the contents of the returned compound strings are implementation dependent. If conversion depends on the locale and the current locale is not supported, the function returns XLocaleNotSupported. If conversion to the encoding of the current locale is required and if the locale is supported but no converter is available for the encoding specified in text_prop, the function returns XConverterNotFound. For supported locales, existence of a converter from COMPOUND_TEXT, STRING, or the encoding of the current locale is guaranteed if XSupportsLocale returns True for the current locale (but the actual text may contain uncon- vertible characters). Conversion of other encodings to the encoding of the current locale is implementation dependent. In all of these error cases, the function does not set any return values. If an element of the value member of text_prop is not convertible to XmString, the corresponding entry in the returned XmStringTable will be NULL, and XmCvtTextPropertyToXmStringTable returns Success. To free the storage for the XmStringTable and its count_return compound strings returned by this function, first free each XmString in the table using XmStringFree, and then free the XmStringTable itself using XtFree. display Specifies the connection to the X server. text_prop Specifies a pointer to the XTextProperty. The format member of text_prop must be 8. string_table_return Specifies the XmStringTable array into which the converted compound strings are placed. count_return Specifies the number of XmStrings returned by this function. RETURN VALUES
Upon success, this function returns the set of XmStrings in string_table_return, and it returns the number of XmStrings in count_return, and returns Success. Otherwise, it returns the following: XLocaleNotSupported Returned if conversion depends on the locale and the current locale is not supported. XConverterNotFound Returned if conversion to the encoding of the current locale is required and if the locale is supported but no converter is available for the encoding specified in text_prop.

Name
  XmbTextPropertyToTextList - convert an internationalized text property to a list of multi-byte strings.

Synopsis
  int XmbTextPropertyToTextList(display, text_prop, list_return, count_return)
	Display *display;
	XTextProperty *text_prop;
	char ***list_return;
	int *count_return;

Arguments
  display   Specifies the connection to the X server.

  text_prop Specifies the XTextProperty structure to be used.

  list_return
	    Returns a list of NULL-terminated character strings.

  count_return
	    Returns the number of strings.

Returns
  Success on success.  XNoMemory, XLocaleNotSupported, or XConverterNotFound on failure.

Availability
  Release 5 and later.

Description
  XmbTextPropertyToTextList()  returns	a  list of multi-byte text strings encoded in the current locale representing the NULL-separated ele-
  ments of the specified XTextProperty structure.  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, XmbTextPropertyToTextList() returns XNoMemory.  If the current locale is
  not supported, it returns XLocaleNotSupported.  If the encoding field of text_prop is not  convertible  to  the  encoding  of  the  current
  locale,  it returns XConverterNotFound.  For supported locales, existence of a converter from COMPOUND_TEXT, STRING, or the encoding of the
  current locale is guaranteed although the actual text may contain unconvertible characters.  Conversion of other encodings  is  implementa-
  tion-dependent.  In all of these error cases, the function does not set any return values.

  Otherwise,  XmbTextPropertyToTextList()  returns 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 function returns the number  of  uncon-
  vertible  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, use XDefaultString().  If all characters are convertible, XmbTextPropertyToTextList() returns  Success.
  If  the  text  property contains "invalid codepoints" or bytes that are not valid characters in the encoding of the property, the result is
  undefined.

  To free the storage for the list and its contents returned by XmbTextPropertyToTextList(), use XFreeStringList().

Structures
  The XTextProperty structure contains:

     typedef struct	    {
	 unsigned char *value;	  /* property data */
	 Atom encoding; 	  /* type of property */
	 int format;		  /* 8, 16, or 32 */
	 unsigned long nitems;	  /* number of items in value */
     } XTextProperty;

  The possible return values of this function are as follows:

#define   XNoMemory		  - 1
#define   XLocaleNotSupported	  - 2
#define   XConverterNotFound	  - 3
