◆ SCIPensureBlockMemoryArray_call()

SCIP_RETCODE SCIPensureBlockMemoryArray_call ( SCIP *  scip,
void **  arrayptr,
size_t  elemsize,
int *  arraysize,
int  minsize 
)

extends a dynamically allocated block memory array to be able to store at least the given number of elements; use SCIPensureBlockMemoryArray() define to call this method!

Returns
SCIP_OKAY is returned if everything worked. Otherwise a suitable error code is passed. See SCIP_RETCODE for a complete list of error codes.
Parameters
scipSCIP data structure
arrayptrpointer to dynamically sized array
elemsizesize in bytes of each element in array
arraysizepointer to current array size
minsizerequired minimal array size
