'void' is assinged in some of the variables

[Prashanth DV]

Hi,
I seeing 'void' is assinged in some of the variables ( job_name & buffer) in gdb output, but I wrote these varibles values to a file, its showing correctly. and also tried to print that via print varable in gdb ..
Any one has any idea ??

Went through each frame/function via gdb & tried to print all local variables, from that I able to find the job name & SQL statement.
But I didn't get the reason why its showing "void" ?
.
thanks,
