Segmentation fault

1 New Member
Hi all,

I´m stuck here. I´m trying to get a single word from an array.
After the text "Sometext10 " comes a word of 6 letters, which I want to get.
I don´t know what is wrong with this code.
I always get segmentation fault, when it comes to run the strncpy command: strncpy (blu,tmp1,len);

Can someone help me with this problem?

Expand|Select|Wrap|Line Numbers
  1. void get_acid(char blu[50])
  2. {
  3.     const char *message = array.text;
  4.     const char *smallstring1 = "Sometext10"; 
  5.     char *ptr1;
  6.  
  7.     ptr1 = strstr(message, smallstring1);
  8.     char *tmp1 = ptr1+10; //beginning of word
  9.     int len = 6; //length of word
  10.     strncpy (blu,tmp1,len);
  11.     blu[len]='\0';
  12. }

Without more context, I would suggest using a debugger or printf statements to determine what is going on. Looks to be that the problem is coming from your caller.

Hi everybody, I'm trying to make the following code running properly, but I can't get rid of the "SEGMENTATION FAULT" error message when executing. Reading some messages posted earlier, I understood that a segmentation fault can occur whenever I declare a pointer and I leave it un-initialized. So I thought the problem here is with the (const char *)s in the stuct flightData (please note that I get the same fault declaring as char * the...

Hi, I'm coming over from Java to C++, so please bear with me. In C++, is there a way for me to use exceptions to catch segmentation faults (e.g. when I access a location off the end of an array)? Thanks.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>". The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed. This is as boiled down as I can make it. Here is my compilation command: g++-12 -std=c++20 -Wnarrowing bit_field.cpp Here is the code in...
