NAME
cxUnkGet
- get information about unknown data structure
C SPECIFICATION
#include <cx/DataAccess.h>
cxErrorCode cxUnkGet(cxUnknown *src, long *count, char *(data[]))
FORTRAN SPECIFICATION
integer function cxUnkGet(src, count, pdata)
integer src
integer count, pdata
pointer (pdata, data)
integer data(*)
PARAMETERS
-
src
-
Input data structure.
-
count
-
Set to number of bytes in src.
-
data
-
Set to first byte of data array.
FUNCTION RETURN VALUE
Returns an integer error code enumeration.
DESCRIPTION
Retrieves information about size and location of data in an IRIS Explorer
cxUnknown data type and stores them in count and data.
cxUnkGet returns cx_err_none on success.
The user can tell the function not to get information on a particular
field by passing a NULL pointer value. You need not create dummy variables
in the calling routine which calls cxUnkGet, because the request is simply ignored
when the pointer comes in NULL.
