#!F-adobe-helvetica-medium-r-normal--18* #!N #!N #!Rdxignhe DXInitGetNextHashElement #!N #!N Function #!N #!N Initializes a pointer for DXGetNextHashElement. #!N #!N Syntax #!N #!F-adobe-times-bold-r-normal--18* #include <dx/dx.h> Error DXInitGetNextHashElement(HashTable hashtable) #!EF #!N #!N Functional Details #!N #!N Generally, a program retrieves entries from a hash table by calling #!F-adobe-times-bold-r-normal--18* DXQueryHashElement #!EF to access arbitrary elements, but sometimes it is convenient to access all elements, regardless of their order. In that case, the program calls #!F-adobe-times-bold-r-normal--18* DXInitGetNextHashElement #!EF to initiate this indexing by initializing the pointer that #!F-adobe-times-bold-r-normal--18* DXGetNextHashElement #!EF uses for iterating #!F-adobe-times-bold-r-normal--18* hashtable #!EF . #!F-adobe-times-bold-r-normal--18* DXInitGetNextElement #!EF initializes the required pointer to zero (0). #!N #!N Return Value #!N #!N Returns #!F-adobe-times-bold-r-normal--18* OK #!EF or returns #!F-adobe-times-bold-r-normal--18* ERROR #!EF and sets an error code. #!N #!N See Also #!N #!N #!F-adobe-times-bold-r-normal--18* #!Ldxch,dxall1190 h DXCreateHash #!EL , #!Ldxgnhe,dxall1251 h DXGetNextHashElement #!EL , #!Ldxihe,dxall1283 h DXInsertHashElement #!EL , #!Ldxqhe,dxall1345 h DXQueryHashElement #!EL #!EF #!N #!N #!Lhash,dxall1121 h Hashing #!EL . #!N #!N #!N #!F-adobe-times-medium-i-normal--18* Next Topic #!EF #!N #!N #!Ldximod,dxall1280 h DXInitModules #!EL #!N #!F-adobe-times-medium-i-normal--18* #!N
