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 ā€™\nā€™ 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).
