XpGetAttributes returns a pool, a COMPOUND_TEXT resource string representing the
attribute pool specified by type. The caller is expected to free pool when it is
no longer needed using XFree.
The attribute pool (hence the resource string) consists of many name-value pairs
(for example, "copy-count: 3"). The syntax of an attribute pool is the same as an
X resource file (see "Resource File Syntax" in the Xlib specification).
Valid characters for each name (left hand side) are derived from the Posix which is
"a"-"z" and "A"="Z" and"0"-"9" and "_" and "-". Valid characters for each value
(right hand side) are all characters except NULL and unescaped NEWLINE, though all
predefined values in the X Print Service are confined to X Portable Character Set
(XPCS) characters. Non XPCS values are typically limited to localized "description"
strings. See XpCreateContext regarding the locale hint for more information on
If any errors occur,
XpGetAttributes returns NULL.
