Hi World,

pstat_getdynamic()function do.

2.)I have statement
struct pst_dynamic pstat_dyn;

rc=pstat_getdynamic(&pstat_dyn,sizeof(struct
pst_dynamic),1,0);

Here rc is equal to -1 what does it mean.
why it is returing -1 value.

Any help is Appreciated.

Hi Gopi:

A return code of -1 signifies a failure. The reason for the failure can be found in 'errno'. If you report 'errno' you can easily examine the 'pstat()' manpages to gain further insight into the reason for the error. See the "ERRORS" section of the manpages.

Hi (again) Gopi:

That's described in the manpages (in the link I provided).
