Help with search <string.h>

What I am trying to do is be able to search for a variable starting with a chosen character using the <string.h> header.

The code so for......

insert

Code:

---


#include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main(int argc, char **argv, char** envp)
{
  char** en;
  for (en = envp; *en != 0; en++)
  {
    char* ce = *en;
    printf("%s\n", ce);     
  }
  system("PAUSE");   
  return 0;
}

Any one help?

That's super easy.... look up the strchr() function in your compiler's library docs.

Using strchr() on your char, will find any instance of the char, but it won't tell you whether the char is the first char of a word.

You may need to separate every word, and then check if word[0]== the char you're looking for.

Thanks for that.

but

That code I have at the moment just prints out the enviroment variables, how can I manipulate the data so I can use strchr to print the result of the search?

What, exactly, are you trying to accomplish with this search?

Are you trying to separate the vairable name from it's data?
Are you trying to find specific variable names?

What?

Sorry for the ambiguity. I am trying to get the enviroment variables as a list and then be able to search for specific variable and output the result.

So maybe, strstr() is what you want. Looks for a string, inside a larger string.
