## Name

ne_buffer — string buffer handling

## Synopsis

    #include <ne_string.h>

    typedef struct {
        char *data;
        size_t used;
        size_t length;
    } ne_buffer;

## Description

The ne_buffer type represents an expandable memory buffer for holding `NUL`-terminated strings. The `data` field points to the beginning of the string, the length of which is given by the `used` field. The current size of memory allocated is given by the `length` field. It is not recommended that the fields of a buffer are manipulated directly. The `data` pointer may change when the buffer is modified.

A buffer is created using ne_buffer_create or ne_buffer_ncreate, and destroyed using ne_buffer_destroy or ne_buffer_finish. The functions ne_buffer_append, ne_buffer_zappend and ne_buffer_concat are used to append data to a buffer.

If the string referenced by the `data` pointer is modified directly (rather than using one of the functions listed above), `ne_buffer_altered` must be called.
