.TH buffer_getline 3
.SH NAME
buffer_getline \- read line from buffer
.SH SYNTAX
.B #include <buffer.h>
int \fBbuffer_getline\fP(buffer* \fIb\fR,char* \fIx\fR,unsigned long int \fIlen\fR);
.SH DESCRIPTION
buffer_getline copies data from \fIb\fR to \fIx\fR[0], \fIx\fR[1], ...,
\fIx\fR[\fIlen\fR-1] until \fIlen\fR bytes have been copied or a
new-line character ('\\n') is encountered. That character is also
copied.
Note that line is not 0-terminated to make reading lines with 0-bytes
possible through this interface.
.SH "RETURN VALUE"
Number of bytes read (without '\\n'), -1 on error (setting \fIerrno\fR).
.SH "SEE ALSO"
buffer_init(3), buffer_feed(3), buffer_peek(3), buffer_seek(3), buffer(3)
