ne_buffer \- string buffer handling
.SH "SYNOPSIS"

.SH "DESCRIPTION"
.PP
The
\fBne_buffer\fR
type represents an expandable memory buffer for holding
NUL\-terminated strings\&. The
\fIdata\fR
field points to the beginning of the string, the length of which is given by the
\fIused\fR
field\&. The current size of memory allocated is given by the
\fIlength\fR
field\&. It is not recommended that the fields of a buffer are manipulated directly\&. The
\fIdata\fR
pointer may change when the buffer is modified\&.
.PP
A buffer is created using
\fBne_buffer_create\fR(3)
or
\fBne_buffer_ncreate\fR(3), and destroyed using
\fBne_buffer_destroy\fR(3)
or
\fBne_buffer_finish\fR(3)\&. The functions
\fBne_buffer_append\fR(3),
\fBne_buffer_zappend\fR(3)
and
\fBne_buffer_concat\fR(3)
are used to append data to a buffer\&.
.PP
If the string referenced by the
\fIdata\fR
pointer is modified directly (rather than using one of the functions listed above),
\fBne_buffer_altered\fR
must be called\&.
