ne_buffer — string buffer handling
#include <ne_string.h> typedef struct { char *data; size_t used; size_t length; } ne_buffer;
The ne_buffer type represents an expandable
memory buffer for holding NUL
-terminated strings. The
data
field points to the beginnning 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.
