simple string editing

I would like to know how to print characters after ')' has been read... I need this to extract the data from a file that contains 100's of .pls files which are used for connecting to web streams, here's what 1 .pls file looks like...

[playlist]
numberofentries=3
File1=http://64.236.34.97:80/stream/1065
Title1=(#1 - 871/18508) D I G I T A L L Y - I M P O R T E D - Vocal Trance - a fusion of trance, dance, and chilling vocals
Length1=-1
File2=http://64.236.34.67:80/stream/1065
Title2=(#2 - 719/14952) D I G I T A L L Y - I M P O R T E D - Vocal Trance - a fusion of trance, dance, and chilling vocals
Length2=-1
File3=http://64.236.34.4:80/stream/1065
Title3=(#3 - 842/16389) D I G I T A L L Y - I M P O R T E D - Vocal Trance - a fusion of trance, dance, and chilling vocals
Length3=-1
Version=2

What i want to get is everything after the Title1=(#1 - 871/18508)

At first I had thought of using strncpy to do this. but if the number of characters in parenthesis changes, that causes a problem.

I also would like to take the address from this by grabbing everything after File1=
I am assuming this is exactly the same as taking everything after ')'

Thank you very much

You can use strchr() to find a specific character within a string.

I am having a hard time understanding how to get the output i want.

I want to say this...

Code:

temp_var = strchr(string, "=");

however what do I declare temp_var as? and how would I print the output. strchr returns a pointer. that is what is confuseing me.

Another possible approach...

Code:

#include <stdio.h>

int main(void)
{
   static const char filename[] = "file.txt";
   FILE *file = fopen(filename, "r");
   if ( file != NULL )
   {
      int ch;
      while ( (ch = getc(file)) != EOF )
      {
         if ( ch == ')' )
         {
            do {
               ch = getc(file);
               if ( ch == EOF )
               {
                  goto done;
               }
               putchar(ch);
            } while ( ch != '\n' );
         }
      }
   done:
      fclose(file);
   }
   else
   {
      perror(filename);
   }
   return 0;
}

Code:

while ( (ch = getc(file)) != EOF )
      {
         if ( ch == ')' )
         {
            do {
               ch = getc(file);
               if ( ch == EOF )
               {
                  goto done;
               }
               putchar(ch);
            } while ( ch != '\n' );
         }
      }

I guess it would not be a good idea to use goto.. instead u can use a break

Yes you will have to adjust the getc(file)..

instead of using it in the while loop you can have it as a statement before it ..
and in the while loop you can just compare (ch!=EOF)
The code given by dave is gr8.. i'm just giving another way of solving the problem..
