Function Documentation

◆ dig_Rd_P_area()

◆ dig_Rd_P_isle()

int dig_Rd_P_isle ( struct Plus_head Plus,
int  n,
struct gvfile fp 
)

◆ dig_Rd_P_line()

◆ dig_Rd_P_node()

◆ dig_Rd_Plus_head()

◆ dig_Wr_P_area()

int dig_Wr_P_area ( struct Plus_head Plus,
int  n,
struct gvfile fp 
)

◆ dig_Wr_P_isle()

int dig_Wr_P_isle ( struct Plus_head Plus,
int  n,
struct gvfile fp 
)

◆ dig_Wr_P_line()

◆ dig_Wr_P_node()

int dig_Wr_P_node ( struct Plus_head Plus,
int  n,
struct gvfile fp 
)

◆ dig_Wr_Plus_head()

int dig_Wr_Plus_head ( struct gvfile fp,
struct Plus_head ptr 
)

Write Plus_head to file.

ptr->off_t_size is used for both coor and topo files, but their sizes (ptr->coor_size for coor and no variable for topo) can be different. If either file is greater than PORT_LONG_MAX, ptr->off_t_size must be 8. This function determines this value of ptr->off_t_size and writes it to the file.

Parameters
fppointer to gvfile structure
[in,out]ptrpointer to Plus_head structure
Returns
-1 error
0 OK
