bson_iter_int64: Fetches the value from a BSON_TYPE_INT64 field. You should verify that this is a BSON_TYPE_INT64 field before calling this function.

NAME

bson_iter_int64() - Fetches the value from a BSON_TYPE_INT64 field. You should verify that this is a BSON_TYPE_INT64 field before calling this function.

SYNOPSIS

#define BSON_ITER_HOLDS_INT64(iter) \
   (bson_iter_type ((iter)) == BSON_TYPE_INT64)

int64_t
bson_iter_int64 (const bson_iter_t *iter);

PARAMETERS

iter
A bson_iter_t \&.

DESCRIPTION

Fetches the value from a BSON_TYPE_INT64 field. You should verify that this is a BSON_TYPE_INT64 field before calling this function.

RETURNS

A 64-bit integer.

Pages related to bson_iter_int64

  • bson_iter_int32 (3) - Fetches the value from a BSON_TYPE_INT32 element. You should verify that the field is a BSON_TYPE_INT32 field before calling this function.
  • bson_iter_init (3) - The bson_iter_init() function shall initialize iter to iterate upon the BSON document bson. Upon initialization, iter is placed before the first element. Callers must call bson_iter_next(), bson_iter_find(), or bson_iter_find_case() to advance to an element.
  • bson_iter_init_find (3) - This function is identical to (bson_iter_init() && bson_iter_find()).
  • bson_iter_init_find_case (3) - This function is identical to bson_iter_init() && bson_iter_find_case().
  • bson_iter_array (3) - The bson_iter_array() function shall retrieve the raw buffer of a sub-array from iter. iter MUST be on an element that is of type BSON_TYPE_ARRAY. This can be verified with bson_iter_type() or the BSON_ITER_HOLDS_ARRAY() macro.
  • bson_iter_as_bool (3) - Fetches the current field as if it were a boolean.
  • bson_iter_as_int64 (3) - The bson_iter_as_int64() function shall return the contents of the current element as if it were a BSON_TYPE_INT64 element. The currently supported casts include:
  • bson_iter_binary (3) - This function shall return the binary data of a BSON_TYPE_BINARY element. It is a programming error to call this function on a field that is not of type BSON_TYPE_BINARY. You can check this with the BSON_ITER_HOLDS_BINARY() macro or bson_iter_type().
  • bson_iter_bool (3) - The bson_iter_bool()function shall return the boolean value of a BSON_TYPE_BOOL element. It is a programming error to call this function on an element other than BSON_TYPE_BOOL. You can check this with bson_iter_type() or BSON_ITER_HOLDS_BOOL().
  • bson_iter_code (3) - This function returns the contents of a BSON_TYPE_CODE field. The length of the string is stored in length if non-NULL.
  • bson_iter_codewscope (3) - The bson_iter_codewscope() function acts similar to bson_iter_code() except for BSON_TYPE_CODEWSCOPE elements. It also will provide a pointer to the buffer for scope, which can be loaded into a bson_t using bson_init_static().
  • bson_iter_date_time (3) - The bson_iter_date_time() function shall return the number of miliseconds since the UNIX epoch, as contained in the BSON_TYPE_DATE_TIME element.
  • bson_iter_dbpointer (3) - Fetches the contents of a BSON_TYPE_DBPOINTER element.
  • bson_iter_document (3) - The bson_iter_document() function shall retrieve the raw buffer of a sub-document from iter. iter MUST be on an element that is of type BSON_TYPE_DOCUMENT. This can be verified with bson_iter_type() or the BSON_ITER_HOLDS_DOCUMENT() macro.
