Synopsis:
#include <sys/pps.h>
pps_decoder_error_t pps_decoder_get_double(
pps_decoder_t *decoder,
const char *name,
double *value);
Arguments:
- decoder
- A pointer to the PPS decoder structure.
- name
- The name of the property to extract the value from. Specify NULL
to extract the data from the current node.
- value
- A pointer to a double to take the result.
Description:
The function pps_decoder_get_double() extracts a double value from the node having
the specified name or, if the name argument is NULL, the current node.
Following successful extraction, the decoder advances to the next node.
Returns:
- PPS_DECODER_OK
- Success.
- PPS_DECODER_DELETED
- The attribute was deleted.
- PPS_DECODER_BAD_TYPE
- There was a type mismatch.
- PPS_DECODER_NOT_FOUND
- The specified node doesn't exist.
- PPS_DECODER_CONVERSION_FAILED
- The value of the attribute is outside the range or would lose precision when converted to the specified type.
