How to use librtc in HP-PA to identify the memory issues

[How to use librtc and i]

Hi,

In sun platform,I used libumem library instead of libc and compiled the code to identify memory issues. Is there any similar kind of a library in HP-UX?
Will librtc solve the above mentioned problem? If yes, what is the usage of librtc.sl in HP PA and HP IA?

Read the wdb documentation:
http://www.hp.com/go/wdb
See: Memory Debugging Capabilities
See the Whitepapers on the documentation link.

This is mainly geared to finding leaks and heap corruption.

[How to use librtc and i]

As per the steps mentioned in http://g4u0420c.houston.hp.com/en/5991-7502/5991-7502.pdf, I tried to execute the batch of debugging for identification of memory leaks. Though, I did not encounter any errors on exeuction of the same, no putput reports of the leaks were obtained.
Can any one help in indetification of the same?

>no output reports of the leaks were obtained.

Start with a trivial program that has leaks:
#include
int main() {
(void)malloc(1000);
return 0;
}

Did you read the Prerequisites in the document?

I used the same example given in that document and still achieved nothing.

This is near useless, what is your gdb, librtc and dld versions?

I don't know if this dld is too old.

>/usr/local/bin/gdb:
Hewlett-Packard Wildebeest 5.3.0 30-Jan-2006

gdb should be in /opt/langtools/bin/gdb.

>librtc.sl:
Hewlett-Packard Wildebeest 5.3.0 30-Jan-2006

You should download the latest wdb.
