int aw_data_set (AW_ATTRIBUTE a, const char *value, unsigned int length)
Description
Sets a data attribute.
Callback
None (returns immediately)
Notes
A few of the data attributes have a maximum length defined by AW_MAX_ATTRIBUTE_LENGTH in Aw.h. This limit is currently 255 bytes. Most attributes can be longer than this (e.g. AW_OBJECT_DATA). Their maximum lengths can vary up to 4094 bytes depending on the attribute (e.g. AW_OBJECT_DATA has a maximum length of 4094 bytes).
See SDK Attributes for more information.
