bson_append_array_begin (3) Linux Manual Page

NAME

bson_append_array_begin() – The bson_append_array_begin() function shall begin appending an array field to bson. This allows for incrementally building a sub-array. Doing so will generally yield better performance as you will serialize to a single buffer. When done building the sub-array, the caller MUST call bson_append_array_end().

SYNOPSIS

bool bson_append_array_begin(bson_t *bson,
                             const char *key,
                             int key_length,
                             bson_t *child);

PARAMETERS

bson

A bson_t \&.

key

A string containing the name for the key.

key_length

The length of key or -1 to call strlen(3) \&.

child

A bson_t \&.

DESCRIPTION

The bson_append_array_begin(3) function shall begin appending an array field to bson \&. This allows for incrementally building a sub-array. Doing so will generally yield better performance as you will serialize to a single buffer. When done building the sub-array, the caller MUST call bson_append_array_end(3) \&.

RETURNS
