I'd like to add a routine similar to GRP_INFOI to HDS that allows me to warn of HDS locator leaks in applications. I think that David's patch to KAPPA to trap GRP ID leaks was useful and it is definitely the case that HDS knows how many locators it has used up. HDS_SHOW would be perfect if only it returned the information to the caller rather than writing it to STDOUT. I propose to try to implement a routine called.... hdsInfoi (wow) that would look something like: hdsInfoi( "LOCATORS", size_t *count, int * status); hdsInfoi( "FILES", size_t * count, int *status); to get the number of active locators and number of open files. Does that API seem reasonable? Given hdsShow, I can make a stab at this. David: Was the "i" in "Infoi" meant to indicate "integer"? -- Tim Jenness JAC software http://www.jach.hawaii.edu/~timj
