Synopsis

int XPRS_CC XPRSgetlasterror(XPRSprob prob, char *errmsg);

Arguments

prob	The current problem.
errmsg	A 512 character buffer where the last error message will be returned.

Example

The following shows how this function might be used in error-checking:

void error(XPRSprob myprob, char *function)
{
  char errmsg[512];
  XPRSgetlasterror(myprob,errmsg);
  printf("Function %s did not execute correctly: %s\n",
         function, errmsg);
  XPRSdestroyprob(myprob);
  XPRSfree();
  exit(1);
}

where the main function might contain lines such as:

XPRSprob prob;
...
if(XPRScreateprob(&prob)) 
  error(prob,"XPRScreateprob");
