Use the strstr() function.

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

  int main(void)
  {
    char *sentence = "the link is http://www.somewhere.org and more words";
    char *http;
    char *space;
    char url[999];

    http = strstr(sentence, "http");

    if(http)
    {
      strcpy(url, http);
      space = strchr(url, ' ');
      if(space)
        *space = 0;
      printf("The url is: %s\n", url);
    }
    else
    {
      printf("http not found in '%s'.\n", sentence);
    }

    return EXIT_SUCCESS;
  }
