Purpose
Returns the names for the
rows,
columns or
set in a given range.
The names will be returned in a character buffer, each name being separated by a null character.
Synopsis
int XPRS_CC XPRSgetnames(XPRSprob prob, int type, char names[], int first, int last);
Arguments
|
prob
|
The current problem.
|
|
type
|
|
1
|
if row names are required;
|
|
2
|
if column names are required.
|
|
3
|
if set names are required.
|
|
|
names
|
Buffer long enough to hold the names. Since each name is 8*NAMELENGTH characters long (plus a null terminator), the array, names, would be required to be at least as long as (first-last+1)*(8*NAMELENGTH+1) characters. The names of the row/column/set first+i will be written into the names buffer starting at position i*8*NAMELENGTH+i.
|
|
first
|
First row, column or set in the range.
|
|
last
|
Last row, column or set in the range.
|
Related Controls
Integer
|
|
Maximum name length in characters.

Example
The following example retrieves the row and column names of the current problem:
int cols, rows, nl;
...
XPRSgetintattrib(prob,XPRS_ORIGINALCOLS,&cols);
XPRSgetintattrib(prob,XPRS_ORIGINALROWS,&rows);
XPRSgetintattrib(prob,XPRS_NAMELENGTH,&nl);
cnames = (char *) malloc(sizeof(char)*(8*nl+1)*cols);
rnames = (char *) malloc(sizeof(char)*(8*nl+1)*rows);
XPRSgetnames(prob,1,rnames,0,rows-1);
XPRSgetnames(prob,2,cnames,0,cols-1);
To display names[i] in C, use
int namelength;
...
XPRSgetintattrib(prob,XPRS_NAMELENGTH,&namelength);
printf("%s",names + i*(8*namelength+1));
