Idiom #49 Split a space-separated string

Build list chunks consisting in substrings of input string s, separated by one or more space characters.

Illustration
Imports 
#include <string.h>
Code 
chunks[0] = strtok(s, " ");
for (int i = 1; i < N; ++i)
{
    chunks[i] = strtok(NULL, " ");
    
    if (!chunks[i])
        break;
}
Comments bubble
N is the size of chunks.

strtok modifies s by adding null-characters between words.
