#!N 
#!N  #!Rdxes DXExtractString #!N 
#!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
