IobjGroup *objGroupNew()

Returns a new object group with the object list set to NULL and an empty string for the name.  Returns NULL for memory error

void objGroupDelete(IobjGroup *group)

Frees group and all its data

void objGroupClear(IobjGroup *group)

Clears out the data in group: frees the object list and sets the name to an empty string

IobjGroup *objGroupDup(IobjGroup *oldGroup)

Returns a duplicate of the object group oldGroup

int objGroupAppend(IobjGroup *group, int ob)

Appends one object number o to group. Returns 1 for memory error

int objGroupLookup(IobjGroup *group, int ob)

Returns the index of object ob if it is in group, otherwise -1

IobjGroup *objGroupListExpand(Ilist **grplistp)

Adds a new object group to the list pointed to by grplistp, allocating a new group list if necessary and returning the address in grplistp. Returns a pointer to the new group or NULL for memory error.

Ilist *objGroupListDup(Ilist *grplist)

Returns a duplicate of the object group list grplist including all its data; returns NULL for error.

void objGroupListDelete(Ilist *grplist)

Frees the object group list grplist and all its data

int objGroupListRemove(Ilist *grplist, int item)

Removes one object group at index item from the group list grplist, freeing its data first.  Returns 1 for inappropriate index.

int objGroupListBytes(Ilist *grplist)

Returns a byte count for the object group list in grplist

double objGroupListChecksum(Ilist *grplist)

Returns a checksum value for the object group list in grplist

int objGroupListWrite(Ilist *grplist, FILE *fout)

Writes the group list grplist to the model file with pointer fout. Returns 1 for error

int objGroupRead(Ilist **grplistp, FILE *fin)

Reads one object group from the model file pointed to by fin into the model imod.  Returns 1 for error.
