|
| Purpose |
|
|
Delete a row specified by name.
|
|
| Synopsis |
|
|
int QSdelete_named_row (QSprob p, const char *rowname)
|
|
| Arguments |
|
p |
|
a handle to an initialized problem. |
rowname |
|
a string specifying the name of a row (constraint) to be deleted. |
|
|
| Returns |
|
|
A zero value if the function terminated correctly, and a non-zero value if an error occurred. If the row is not in the LP problem, an error will be returned.
|
|
| Description |
|
|
Use this function to delete a single constraint from an existing LP problem by specifying the name of the constraint; the interface is slightly easier than that of QSdelete_named_rows_list.
|
|
| Example |
|
|
/* Assume p is an initialized LP problem. */
/* Delete constraint r2. */
int rval;
rval = QSdelete_named_row (p, "r2");
if (rval) {
fprintf (stderr, "could not delete row, error code %d\n", rval);
}
