.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 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.
|
||
|
|
|
||
|
|
buffer_getline returns the number of bytes read (excluding the '\\n') or
|
||
|
|
-1 on error (setting \fIerrno\fR appropriately).
|
||
|
|
|
||
|
|
Note that line is not 0-terminated to make reading lines with 0-bytes
|
||
|
|
possible through this interface.
