C --*** DBIELB *** (EXOLIB) Read database element blocks
|
|
C -- Written by Amy Gilkey - revised 10/14/87
|
|
C --
|
|
C --DBIELB reads the element block information from the database.
|
|
C --An error message is displayed if the end of file is read.
|
|
C --
|
|
C --The dynamic memory arrays LINK and ATRIB must be reserved
|
|
C --if the connectivity and attributes are to be stored. These arrays
|
|
C --will be expanded by this routine to hold the new data.
|
|
C --
|
|
C --Parameters:
|
|
C -- NDB - IN - the database file
|
|
C -- OPTION - IN - ' ' to not store, '*' to store all, else store options:
|
|
C -- 'H' to store all header information
|
|
C -- 'I' to store block IDs
|
|
C -- 'C' to store connectivity (+ NUMLNK + NUMELB)
|
|
C -- 'A' to store attributes (+ NUMATR + NUMELB)
|
|
C -- NELBS, NELBE - IN - the number of first and last element blocks
|
|
C -- to read
|
|
C -- IDELB - OUT - the element block IDs for each block (if OPTION)
|
|
C -- NUMELB - OUT - the number of elements in each block (if OPTION)
|
|
C -- NUMLNK - OUT - the number of nodes per element in each block
|
|
C -- (if OPTION)
|
|
C -- NUMATR - OUT - the number of attributes in each block (if OPTION)
|
|
C -- A - IN/OUT - the dynamic memory base array
|
|
C -- KLINK - OUT - pointer to the connectivity for each block (if OPTION)
|
|
C -- KATRIB - OUT - pointer to the attributes for each block (if OPTION)
|
|
C -- * - return statement if end of file or read error
|
|
C --
|
|
C --Database must be positioned at start of element block information
|
|
C --upon entry; upon exit at end of element block information.
