buffer_getline_sa(3) Library Functions Manual buffer_getline_sa(3) NAME buffer_getline_sa - read line from buffer SYNTAX #include <libowfat/stralloc.h> #include <libowfat/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).
