Synopsis
int XPRS_CC XPRSgetindex(XPRSprob prob, int type, const char *name, int *p_index);
Arguments
prob 
The current problem.
type 
XPRS_NAMES_ROW 
(=1) if row index is required;
XPRS_NAMES_COLUMN 
(=2) if column index is required;
XPRS_NAMES_SET 
(=3) if set index is required;
XPRS_NAMES_PWLCONS 
(=4) if piecewise linear constraint index is required;
XPRS_NAMES_GENCONS 
(=5) if general constraint index is required;
XPRS_NAMES_OBJECTIVE 
(=6) if objective index is required;
XPRS_NAMES_USERFUNC 
(=7) if user function index is required;
XPRS_NAMES_INTERNALFUNC 
(=8) if an internal function index is required.
name 
Null terminated string.
p_index 
Pointer of the integer where the row or column index number will be returned. A value of -1 will be returned if the row or column does not exist.
Example
The following example loads problem and checks to see if " n 0203" is the name of a row or column: 
int seqr, seqc;
...
XPRSreadprob(prob,"problem","");

XPRSgetindex(prob,1,"n   0203", &seqr);
XPRSgetindex(prob,2,"n   0203", &seqc);
if(seqr==-1 && seqc ==-1) printf("n   0203 not there\n");
if(seqr!= -1) printf("n   0203 is row %d\n",seqr);
if(seqc!= -1) printf"n   0203 is column %d\n",seqc);
