extran NUll character added after end of line "\n"
Hi All,
I am facing a strange situation and want to find why it is occuring . When i convert the whole line into Hexadecimal character i can find the junk value after new line (\n) . If i look in binary mode it is not visible.
PLease let me know how possible the junk character is added after new line.
PLease look at the below two lines . The red is the actual line and the blue isthe hexa decimal converted line
0000000 3030 3231 3234 3531 3033 3838 7c31 3337 0000010 3230 7c53 7c 0a
0 0 2 1 2 4 5 1 0 3 8 8 | 1 3 7 2 0 | S
| \n
0000000 3036 3838 3934 3330 3836 3036 207c 3133 0000010 3732 317c 537c 0a 00
0 6 8 8 9 4 3 0 8 6 0 6 | 1 3 7 2 1 | S |

strfind
strfind(3GEN) String Pattern-Matching Library Functions strfind(3GEN)
NAME
strfind, strrspn, strtrns, str - string manipulations
SYNOPSIS
cc [ flag ... ] file ... -lgen [ library ... ]
#include <libgen.h>
int strfind(const char *as1, const char *as2);
char *strrspn(const char *string, const char *tc);
char * strtrns(const char *string, const char *old, const char *new,
char *result);
DESCRIPTION
The strfind() function returns the offset of the first occurrence of the second string, as2, if it is a substring of string as1. If the
second string is not a substring of the first string strfind() returns -1.
The strrspn() function trims chartacters from a string. It searches from the end of string for the first character that is not contained in
tc. If such a character is found, strrspn() returns a pointer to the next character; otherwise, it returns a pointer to string.
The strtrns() function transforms string and copies it into result. Any character that appears in old is replaced with the character
in the same position in new. The new result is returned.
USAGE
When compiling multithreaded applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in mul-
tithreaded applications.
EXAMPLES
Example 1 An example of the strfind() function.
/* find offset to substring "hello" within as1 */
i = strfind(as1, "hello");
/* trim junk from end of string */
s2 = strrspn(s1, "*?#$%");
*s2 = '
