NAME
buffer_getline_sa - read line from bufferSYNTAX
#include <stralloc.h> #include <buffer.h> int buffer_getline_sa(buffer* b,stralloc* sa);
DESCRIPTION
buffer_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.
RETURN VALUE
-1 on error (setting errno), 0 on EOF, 1 when successful.RATIONALE
buffer_getline_sa appends instead of overwriting so it can be used on non-blocking sockets (these signal error and set errno to EAGAIN; in this case you can simply call buffer_getline_sa again when select or poll indicate more data is available).SEE ALSO
