NAME

mongoc_collection_command() - This function shall execute a command on a collection. This is performed lazily and therefore requires calling mongoc_cursor_next() on the resulting cursor structure. The cursor should be freed with mongoc_cursor_destroy() when no longer in use.

SYNOPSIS

mongoc_cursor_t *
mongoc_collection_command (mongoc_collection_t       *collection,
                           mongoc_query_flags_t       flags,
                           uint32_t                   skip,
                           uint32_t                   limit,
                           uint32_t                   batch_size,
                           const bson_t              *command,
                           const bson_t              *fields,
                           const mongoc_read_prefs_t *read_prefs)
BSON_GNUC_WARN_UNUSED_RESULT;

PARAMETERS

collection
A mongoc_collection_t \&.

flags
A mongoc_query_flags_t \&.

skip
A uint32_t with the number of documents to skip or zero.

limit
A uint32_t with the max number of documents to return or zero.

batch_size
A uint32_t with the number of documents in each batch or zero. Default is 100.

command
A bson_t containing the command to execute.

fields
A bson_t containing the fields to return or NULL \&. Not all commands support this option.

read_prefs
A mongoc_read_prefs_t or NULL \&.

DESCRIPTION

This function shall execute a command on a collection. This is performed lazily and therefore requires calling mongoc_cursor_next(3) on the resulting cursor structure. The cursor should be freed with mongoc_cursor_destroy(3) when no longer in use.

RETURNS

A lazy mongoc_cursor_t that should be freed with mongoc_cursor_destroy(3) \&.

NOTE

Failure to handle the result of this function is a programming error.
