Hi Don..
Apologies for not "specifying" correctly.
1>Well Blank Line would mean spaces and tabs only.
2>Blank records in between "|" delimiter means that the column is NULL (blank as of now) . User has forgot to place the data there.
Example ABCDEFGH|"NULL"|M|"NULL"
"NULL"|XYZABNH|"NULL"|4567344
3>Junk Characters would mean characters other that alphabets or numerical or special characters. Something which is not understandable.
Example ¢'Á|äÃ
"
KJHSAJKHHJJ" or "ABCDEFGH" are examples which I have used instead of proper names.

wcstok
WCSTOK(3) Linux Programmer's Manual WCSTOK(3)
NAME
wcstok - split wide-character string into tokens
SYNOPSIS
#include <wchar.h>
wchar_t *wcstok(wchar_t *wcs, const wchar_t *delim, wchar_t **ptr);
DESCRIPTION
The wcstok function is the wide-character equivalent of the strtok function, with an added argument to make it multithread-safe. It can be
used to split a wide-character string wcs into tokens, where a token is defined as a substring not containing any wide-characters from
delim.
The search starts at wcs, if wcs is not NULL, or at *ptr, if wcs is NULL. First, any delimiter wide-characters are skipped, i.e. the
pointer is advanced beyond any wide-characters which occur in delim. If the end of the wide-character string is now reached, wcstok
returns NULL, to indicate that no tokens were found, and stores an appropriate value in *ptr, so that subsequent calls to wcstok will con-
tinue to return NULL. Otherwise, the wcstok function recognizes the beginning of a token and returns a pointer to it, but before doing
that, it zero-terminates the token by replacing the next wide-character which occurs in delim with a L'
