A way to get around this (for demonstration sake, because
Code:
done < STG_INSTNCE_COMPLTED_01_451_20170112193018.log

is the superior approach to UUOC and there are better ways than using the grep -i inside the loop):
Code:
fnct_dae_V1 ()
{
  var=0
  cat "STG_INSTNCE_COMPLTED_01_451_20170112193018.log" | 
  {
    while read -r line
    do
      if [[ $(echo "$line" | grep -i 'completed') ]]
      then
        ((var++))
        echo "- INSIDE WHILE:var:$var"
      fi
    done
    echo "- OUTSIDE WHILE:var:$var"
  }
}

sched_getparam

sched_getparam(3C)					   Standard C Library Functions 					sched_getparam(3C)

NAME

       sched_getparam - get scheduling parameters

SYNOPSIS

       #include <sched.h>

       int sched_getparam(pid_t pid, struct sched_param *param);

DESCRIPTION

       The  sched_getparam()  function	returns the scheduling parameters of a process specified by pid in the sched_param structure pointed to by
       param. The only required member of param is sched_priority.

       If a process specified by pid exists and if the calling process has permission, the scheduling parameters for the process whose process	ID
       is equal to pid will be returned.

       If  pid is 0, the scheduling parameters for the calling process will be returned. The behavior of the sched_getparam() function is unspeci-
       fied if the value of pid is negative.

RETURN VALUES

       Upon successful completion, the sched_getparam() function returns 0. If the call to sched_getparam() is unsuccessful, the function  returns
       -1 and sets errno to indicate the error.

ERRORS

       The  sched_getparam() function will fail if:

       EPERM	The requesting process does not have permission to obtain the scheduling parameters of the specified process.

       ESRCH	No process can be found corresponding to that specified by pid.
