ne_buffer_clear, ne_buffer_grow, ne_buffer_altered — clear, grow, or mark as altered a string buffer


#include <ne_string.h>
void ne_buffer_clear(ne_buffer *buf);
void ne_buffer_altered(ne_buffer *buf);
void ne_buffer_grow(ne_buffer *buf,
 size_t size);


The ne_buffer_clear function sets the string stored in buf to be the empty string ("").

The ne_buffer_altered function must be used after the string stored in the buffer buf is modified by directly rather than using ne_buffer_append, ne_buffer_zappend or ne_buffer_concat.

The ne_buffer_grow function ensures that at least size bytes are allocated for the string; this can be used if a large amount of data is going to be appended to the buffer and may result in more efficient memory allocation.
