String Building Abstraction
.SH SYNOPSIS

.INDENT 3.5

#include <bson/bson.h>

typedef struct {
   char *str;

.SH DESCRIPTION
.sp
\fI\%bson_string_t\fP is an abstraction for building strings. As chunks are added to the string, allocations are performed in powers of two.
.sp
This API is useful if you need to build UTF\-8 encoded strings.
.SH EXAMPLE
.INDENT 0.0
.INDENT 3.5
.sp
.EX
bson_string_t *str;

str = bson_string_new (NULL);
bson_string_append_printf (str, \(dq%d %s %f\en\(dq, 0, \(dqsome string\(dq, 0.123);
printf (\(dq%s\en\(dq, str\->str);

bson_string_free (str, true);

You can call \fI\%bson_string_free()\fP with \fBfalse\fP if you would like to take ownership of \fBstr\->str\fP\&. Some APIs that do this might call \fBreturn bson_string_free (str, false);\fP after building the string.
