I am trying to read file with 30 rows and 5 columns with separator of "tab". Each time I get only part of the rows.
In the windows environment it's working good. Any idea why in unix it is not working?
while (fscanf(FFMapFile, "%s\t%s\t%s\t%s\t%s\t", fnfMap[i].COS_ID, fnfMap[i].FF_First_Act, fnfMap[i].FF_Next_Act, nfMap[i].Free_FF_allo...
I am trying to read in a certain portion of a file and that amount of data is different per line but I know how how many bytes of info I want. Like this:
5bytes.byte1byte2byte3byte4byte5CKSum //where # of bytes varies for each line (and there is no period only there for readability)
Actual data:
05AABBCCDDEE11
03AABBCC22

I wrote up a quick memory reader class that emulates the same functions as fread and fscanf.
Basically, I used memcpy and increased an internal pointer to read the data like fread, but I have a fscanf_s call. I used sscanf_s, except that doesn't tell me how many bytes it read out of the data.
Is there a way to tell how many bytes ssc...
I am reading in a file with multiple lines of data like this:
:100093000202C4C0E0E57FB40005D0E0020C03B463
:1000A3000105D0E0022803B40205D0E0027C03027C
:1000B30002E3C0E0E57FB40005D0E0020C0BB4011D
I am reading in values byte by byte and storing them in an array.
fscanf_s(in_file,"%c", &sc); // start code

I need to read and print data from a file.
I wrote the program like below,
#include<stdio.h>
#include<conio.h>
int main(void)

char item[9], status;
FILE *fp;
if( (fp = fopen("D:\\Sample\\database.txt", "r+")) == NULL)
{
printf("No such file\n");
exit(1);
}
if (fp == NULL)
{
printf("Error Reading File\n");
}

Hi there,
I have some lines I want to parse from a text file. Some lines start with x and continue with several y:z and others are composed completely of several y:zs, where x,y,z are numbers. I tried following code, but it does not work. The first line also reads in the y in y:z.

if (fscanf(stream,"%d ",&x))
if else (fscanf(strea...
Hello, I want to open a file for both writing and reading, but after I read from it I can't write:
f_prefs = fopen(prefs_path, "r+");
while (fscanf(f_prefs, "%[^\n]\n", line) == 1)
{
... do some stuff ...
fprintf(f_prefs, "test"); // doesn't work
...
}
Any ideas?

Hi,
I've done many simple procedures, but I'm only trying to read the first word into a char word[30] , from each line of a text file.
I've tried, but without success. Oh, I have to reuse that char each time I read it. (To put in an ordered list each time I read it).
Can anyone help me and show me a way to read this way from a file, i...
I am attempting to parse a text (CSS) file using fscanf and pull out all statements that match this pattern:
@import "some/file/somewhere.css";
To do this, I have the following loop set up:
FILE *file = fopen(pathToSomeFile, "r");
char *buffer = (char *)malloc(sizeof(char) * 9000);
while(!feof(file))
{
// %*[^@] : Read and discar...
If I open a file and use fscanf to read a file like this:

How do I tell C to read the first number and store it as a variable, then the second as another variable, run a loop, then move on to the next set?

I've got a C program that encounters errors when I enter a while loop.
I initialize a variable (fragmentcount) and write into it using fscanf and assign it a value of 4 (this works)
int fragmentCount;
if ((fscanf(fp, "%i", &fragmentCount)) == 1) {
...
}
However, when I try to access it in a while loop below, fragmentCount = 0
