#!N Function #!N #!N Determines whether an Object can be converted
to a String, and if so, extracts it. #!N #!N Syntax
#!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Object DXExtractString(Object o, char **cp) #!EF #!N
#!N Functional Details #!N #!N If Object #!F-adobe-times-bold-r-normal--18* o #!EF contains
a string, the routine extracts it and places a pointer to
its first character in #!F-adobe-times-bold-r-normal--18* *cp #!EF . Strings may be
extracted from any of the following: #!N #!I0 #!N #!F-adobe-times-medium-r-normal--18* #!N
#!N #!I30 #!N o String Objects #!N #!I30 #!N o String
lists containing a single element, such as those created by #!F-adobe-times-bold-r-normal--18*
DXMakeStringList #!EF and #!F-adobe-times-bold-r-normal--18* DXMakeStringListV #!EF #!N #!I30 #!N o Array
Objects containing data of Type #!F-adobe-times-bold-r-normal--18* TYPE_UBYTE #!EF with a single
#!F-adobe-times-bold-r-normal--18* NULL #!EF at the end and no embedded #!F-adobe-times-bold-r-normal--18* NULLS
#!EF . This is for backward compatibility only; its use is
#!F-adobe-times-medium-i-normal--18* not #!EF recommended. #!N #!I0 #!N #!EF #!N #!N #!N
Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* o #!EF and sets #!F-adobe-times-bold-r-normal--18*
cp #!EF if a string can be extracted from #!F-adobe-times-bold-r-normal--18* o
#!EF ; otherwise, returns #!F-adobe-times-bold-r-normal--18* NULL #!EF without setting an error
