QNX SDP8.0JSON Library ReferenceAPIDeveloper
Determine if a node represents an integer value
Synopsis:
#include <sys/json.h>bool json_decoder_is_integer(json_decoder_t *decoder,
const char *name)Arguments:
- decoder
- The JSON decoder instance.
- name
- The name of the node to test, or NULL to test the current node.
Library:
libjsonDescription:
This function returns true if the value of the specified or current node can be returned using json_decoder_get_int_ll(), or false otherwise.
Four functions can return numeric values: json_decoder_get_int(), json_decoder_get_int_ll(), json_decoder_get_int_ull(), and json_decoder_get_double(). The underlying value determines which of these functions can return the value without error. Call this function to test whether the value is an integer and is within the range of a long long.
Returns:
true- The node represents an integer value that can be accessed using json_decoder_get_int_ll().false- The node's value cannot be returned by calling json_decoder_get_int_ll().
