| pe_predefined_vdatum | |
Creates a table of predefined vertical datums
PE_TABLE pe_predefined_vdatum(int *n);
| n | The number of rows in the table is returned in this parameter |
The table is an array of rows with the following structure:
typedef struct pe_entry_t
{
int code;
char name[PE_NAME_MAX];
} *PE_TABLE;
If PEOBJEDITHOME is set, the table will include user-defined vertical datum objects. Free the table with pe_table_del.
On success, the table; on failure, a null pointer
PE_TABLE vvdatums;
int n, i;
vdatums = pe_predefined_vdatum(&n);
for ( i=0; i<n; i++ )
{
printf("%d %s\n",datums[i].code,vdatums[i].name);
}
