Error Expected Declaration Specifiers Or ‘...’ Before ‘size_t’

learning the C language in college so this is a homework assignment but I have a small problem. I'm guessing I've just misjudged the syntax or are missing something really obvious. My compiler is telling me that there is: expected declaration specifiers or "..." before constant and pointing to the O_RDWR. I've googled and searched on Stack Exchange but there doesn't seem anything specific to it. Following the syntax error expected declaration specifiers or ‘...’ before ‘znode op’ in a C reference it's fine. I've looked around and it says I have not predefined the typedef but I've tried that to no avail. I've starred the section that is causing the problem according to the compiler with ** #include #include #include #include #include int main (int argc, char *argv[]) { int count; printf ("This program was called \"%s\".\n",argv[0]); if (argc > 1) { for (count = 1; count < argc; count++) { printf("argv[%d] = %s\n", count, argv[count]); } } else { printf("The command had no arguments.\n"); } if (argc == 4) { printf("There are the correct number of arguments(4)"); } else { printf("Not enough arguments! please try again"); } **int open(const char *argv[1], O_RDWR); return 0;** } c file-io share|improve this question edited Feb 17 '14 at 21:43 Tshepang 4,6841059103 asked Sep 20 '12 at 23:10 Timothy Ford 54211 +1: I wish all the new user homework questions were like this.

The former is a standard

And where is Line 8, 21? –Devolus Dec 31 '13 at 16:23 Shot in the dark: I assume one of the headers you included contains a definement for RGB. Rename the function and see if that helps. –Christopher Creutzig Dec 31 '13 at 16:24 @Devolus because it's a snippet? –Thomas Ayoub Dec 31 '13 at 16:24 Looks like RGB is a type or macro trying to find more info. –Shafik Yaghmour Dec 31 '13 at 16:24 add a comment| 1 Answer 1 active oldest votes up vote 4 down vote accepted Looks like RGB is a macro, if you rename the function that error will go away. Also Set_Color needs to return a value you have it defined to return an int but you fall of the end of the function without returning anything. If you attempted to use the value of Set_Color without an explicit return that would be undefined behavior as per the C99 draft standard section 6.9.1 Function definitions paragraph 12: If the } that terminates a function is reached, and the
