.SH NAME
buffer_get_new_token_sa \- read token from buffer
.SH SYNTAX
.nf
.B #include <libowfat/stralloc.h>
.B #include <libowfat/buffer.h>

int \fBbuffer_get_new_token_sa\fP(buffer* \fIb\fR,stralloc* \fIsa\fR,
                    const char* \fIcharset\fR,size_t \fIsetlen\fR);
.SH DESCRIPTION
buffer_get_new_token_sa copies data from the \fIb\fR to \fIsa\fR until
one of the delimiters in \fIcharset\fR is found, overwriting the
previous content of \fIsa\fR.  That delimiter is also copied to
\fIsa\fR.

If reading from the buffer or allocating memory fails,
buffer_get_new_token_sa returns -1 and sets \fIerrno\fR appropriately.  At
that point \fIsa\fR may already contain a partial token.

If you want to read from a non-blocking socket, use buffer_get_token_sa
instead.
.SH "RETURN VALUE"
-1 on error (setting errno), 0 on EOF, 1 when successful.
