NAME

       XStringListToTextProperty, XTextPropertyToStringList, XFreeStringList, XTextProperty -
       convert string lists and text property structure

SYNTAX

       Status XStringListToTextProperty(char **list, int count, XTextProperty *text_prop_return);

       Status XTextPropertyToStringList(XTextProperty *text_prop, char ***list_return, int
              *count_return);

       void XFreeStringList(char **list);

ARGUMENTS

       count     Specifies the number of strings.

       count_return
                 Returns the number of strings.

       list      Specifies the list of strings to be freed.

       list      Specifies a list of null-terminated character strings.

       list_return
                 Returns a list of null-terminated character strings.

       text_prop Specifies the XTextProperty structure to be used.

       text_prop_return
                 Returns the XTextProperty structure.

DESCRIPTION

       The XStringListToTextProperty function sets the specified XTextProperty to be of type
       STRING (format 8) with a value representing the concatenation of the specified list of
       null-separated character strings.  An extra null byte (which is not included in the nitems
       member) is stored at the end of the value field of text_prop_return.  The strings are
       assumed (without verification) to be in the STRING encoding.  If insufficient memory is
       available for the new value string, XStringListToTextProperty does not set any fields in
       the XTextProperty structure and returns a zero status.  Otherwise, it returns a nonzero
       status.  To free the storage for the value field, use XFree.

       The XTextPropertyToStringList function returns a list of strings representing the null-
       separated elements of the specified XTextProperty structure.  The data in text_prop must
       be of type STRING and format 8.  Multiple elements of the property (for example, the
       strings in a disjoint text selection) are separated by NULL (encoding 0).  The contents of
       the property are not null-terminated.  If insufficient memory is available for the list
       and its elements, XTextPropertyToStringList sets no return values and returns a zero
       status.  Otherwise, it returns a nonzero status.  To free the storage for the list and its
       contents, use XFreeStringList.

       The XFreeStringList function releases memory allocated by XmbTextPropertyToTextList,
       Xutf8TextPropertyToTextList and XTextPropertyToStringList and the missing charset list
       allocated by XCreateFontSet.

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;
