#include <stralloc.h> #include <buffer.h> int buffer_getline_sa(buffer* b,stralloc* sa);
DESCRIPTIONbuffer_getline_sa appends data from the b to sa until a '\n' is found, NOT overwriting the previous content of sa. The new-line is also appended to sa.
If reading from the buffer or allocating memory fails, buffer_getline_sa returns -1 and sets errno appropriately. At that point sa may be empty or it may already contain a partial token.
