[Darshan-users] Problem with darshan_log_getmounts and darshan_log_getexe

[Matthieu Dorier]

Hi, 


I'm using the C API of Darshan and I have some problems with the two functions mentioned in the title of this mail. 
I'm testing them using 10024744407537054797.bz2 (in http://ftp.mcs.anl.gov/pub/darshan/data/intrepid/2012/9/1/). 
This trace is supposed to show 4 mount points, which I see when using the darshan-parse command line tool, yet darshan_log_getmounts gives me 0 mount points. 
The "exe" field is supposed to contain "3979759305", but when calling darshan_log_getexe I get the string "2.02". 
These functions do not return any error code. 


All other functions are working properly. I'm using version 2.2.5 of Darshan. 


Just to check, here is how I use these functions: 


int64_t** devs; 
char*** mnt_pts; 
char*** fs_types; 
int count; 
int err = darshan_log_getmounts(fd,devs,mnt_pts,fs_types,&count); 
// here c = 0 
free(devs); free(mnt_pts); free(fs_types); 


char buffer[CP_EXE_LEN+2]; 
darshan_log_getexe(fd, buffer); 


Is there a bug somewhere or am I misusing these functions? 
Thanks!
