Declaration [src]

void
arv_chunk_parser_set_integer_feature_value (
  ArvChunkParser* parser,
  const char* feature,
  gint64 value,
  GError** error
)

Description [src]

Set a feature value using a 64 bit value. The main use for this function is to set a Selector feature, in order to access the corresponding chunk value. As the Genicam data owned by the parser is not shared with the device, this function is limited to features that don’t trigger device access.

Available since: 0.8.35

Parameters

feature

Type: const char*

Feature name.

The data is owned by the caller of the method.

The value is a NUL terminated UTF-8 string.

value

Type: gint64

Feature value.

error

Type: GError **

The return location for a recoverable error.

The argument can be NULL.

If the return location is not NULL, then you must initialize it to a NULL GError*.

The argument will be left initialized to NULL by the method if there are no errors.

In case of error, the argument will be set to a newly allocated GError; the caller will take ownership of the data, and be responsible for freeing it.
