## Name

ne_buffer_append, ne_buffer_zappend, ne_buffer_concat — append data to a string buffer

## Synopsis

    #include <ne_string.h>

``void ne_buffer_append(`ne_buffer *buf, const char *string, size_t len`)`;`
``void ne_buffer_zappend(`ne_buffer *buf, const char *string`)`;`
``void ne_buffer_concat(`ne_buffer *buf, const char *str, ...`)`;`

## Description

The `ne_buffer_append` and `ne_buffer_zappend` functions append a string to the end of a buffer; extending the buffer as necessary. The `len` passed to `ne_buffer_append` specifies the length of the string to append; there must be no `NUL` terminator in the first `len` bytes of the string. `ne_buffer_zappend` must be passed a `NUL`-terminated string.

The `ne_buffer_concat` function takes a variable-length argument list following `str`; each argument must be a char * pointer to a `NUL`-terminated string. A `NULL` pointer must be given as the last argument to mark the end of the list. The strings (including `str`) are appended to the buffer in the order given. None of the strings passed to `ne_buffer_concat` are modified.

## Examples

The following code will output "`Hello, world. And goodbye.`".

    ne_buffer *buf = ne_buffer_create();
    ne_buffer_zappend(buf, "Hello");
    ne_buffer_concat(buf, ", world. ", "And ", "goodbye.", NULL);
    puts(buf->data);
    ne_buffer_destroy(buf);
