Purpose
Synopsis
void *getnextcol(XPRMcontext ctx, void *adr, XPRMmpvar *var, int *col);
Arguments
|
ctx
|
Mosel's execution context
|
|
adr
|
Value returned by the previous call to this function or
NULL for the first call
|
|
var
|
A pointer to return the variable reference
|
|
col
|
A pointer to return the column number
|
Return value
The value to be used as the
adr parameter for a subsequent call or
NULL when all columns have been enumerated.
Example
/* Display column names */
void dispcolnames(XPRMcontext ctx)
{
void *ptr;
XPRMmpvar v;
int ndx;
if(mmx->getmatsolv(ctx, NULL, NULL)<3)
{ /* only if a problem exists */
mmx->genmpnames(ctx, XPRM_KEEPOBJ, NULL, 0);
ptr=NULL;
while((ptr=mmx->getnextcol(ctx, ptr, &v, &ndx))!=NULL)
mm->printf(ctx, "%p=%s\n", v,
mmx->getmpname(ctx, XPRM_MPNAM_COL, ndx));
}
}
Further information
This function returns the next column information (decision variable reference and column number) in the matrix. The second parameter is used to store the current location in the table: the value returned by the function has to be used as input for the subsequent call until the function returns
NULL.
