bson_append_array_begin (3) - Linux Manuals

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().

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

true if the operation was applied successfully, otherwise false and bson should be discarded.
