Hello, I have formatted lines delimited by colon ":", and I need to parse the line into two parts with sscanf() with format specifiers.
infile.txt:
And here is my code fragment:
There may not be space/tab before or after the colon. Ignoring the float/integer data type for numbers at this moment.
For each line I could not get the first half to name, and the first part after ":" into str1. The problem is sscanf() does not stop at the end of each line. Spent some time reading the manpage of sscanf() and my old post, could not figure it out myself.
What is wrong with my sscanf() line? Thanks a lot.

Hi all,
My simple AWK code does C = A - B
If C can be a negative number, how awk printf formating handles it using string format specifier.
Thanks in advance

I need to match a float inside a very long string (about 5000 chars) with sscanf. (I trimmed the string in this example.) I can't seem to match all the chars that come before and after the float.

char A = "";

sscanf does not stop at the first "&". How can I extract "doe" ?
char A = "name=john&last=doe&job=vacant&";
char B = "last";
char C = "";
char *POINTER = strstr(A, B);
sscanf(POINTER + strlen(B), "=%s%*", C);
printf("%s\n", C); // doe&job=vacant& (2 Replies)
How can I separetely extract the string and int after "dribble" ? (sscanf must limit TEXT to 9 chars to avoid buffer overflows.)

{
char TEXT = "";
int NUMBER = 0;

wsscanf
wsscanf(3C) Standard C Library Functions wsscanf(3C)NAME
wsscanf - formatted input conversion
SYNOPSIS
#include<stdio.h>
#include <widec.h>
int wsscanf(wchar_t *s, const char *format, /* pointer */ ... );
DESCRIPTION
The wsscanf() function reads Process Code characters from the Process Code string s, interprets them according to the format, and stores
the results in its arguments. It expects, as arguments, a control string format, and a set of pointer arguments indicating where the con-
verted input should be stored. The results are undefined if there are insufficient args for the format. If the format is exhausted while
args remain, the excess args are simply ignored.
The conversion specifications and behavior of wsscanf() are the same as the regular sscanf(3C) function except that the source is a Process
Code string for wsscanf() and on Extended Unix Code (EUC) character string for sscanf(3C).
RETURN VALUES
Upon successful completion, wsscanf() returns the number of characters matched. Otherwise, it returns a negative value.
