XSLPgetindex

---

Purpose

Retrieve the index of an Xpress-SLP entity with a given name

Synopsis

int XPRS_CC XSLPgetindex(XSLPprob Prob, int Type, char *cName, int *Index);

Arguments

Prob	The current SLP problem.
Type	Type of entity. The following are defined: XSLP_CVNAMES  (=3) Character variables; XSLP_XVNAMES  (=4) Extended variable arrays; XSLP_USERFUNCNAMES  (=5) User functions; XSLP_INTERNALFUNCNAMES  (=6) Internal functions; XSLP_USERFUNCNAMESNOCASE  (=7) User functions, case insensitive; XSLP_INTERNALFUNCNAMESNOCASE  (=8) Internal functions, case insensitive; The constants 1 (for row names) and 2 (for column names) may also be used.
cName	Character string containing the name, terminated by a null character.
Index	Integer to receive the index of the item.

Example

The following example retrieves the index of the internal SIN function using both an upper-case and a lower case version of the name.

int UpperIndex, LowerIndex;
XSLPgetindex(Prob, XSLP_INTERNALFUNCNAMESNOCASE,
             "SIN", &UpperIndex);
XSLPgetindex(Prob, XSLP_INTERNALFUNCNAMESNOCASE,
             "sin", &LowerIndex);

UpperIndex and LowerIndex will contain the same value because the search was made using case-insensitive matching.

Further information

All entities count from 1. This includes the use of 1 or 2 (row or column) for Type which ignore the setting of XPRS_CSTYLE. A value of zero returned in Index means there is no matching item. The case-insensitive types will find the first match regardless of the case of cName or of the defined function.
