c - Searching for \n\n in a returned message -

i'm writing program emulating linux command, return msg contains file , header separated \n\n inside message. thing i'm not sure how search returned string , find message, because \n signifies string has ended. if can lead me on correct path awesome.

in c, assuming talking 0 terminated strings (the norm), \0 (i.e. nul character, i.e. zero) indicates string has ended, not \n.

you can search 2 \n using strstr function. man page:

   #include <string.h>     char *strstr(const char *haystack, const char *needle); 

so like:

char *found; found = strstr (string_to_search, "\n\n");
