int aw_string_set (AW_ATTRIBUTE a, char *value)
Description
Sets a string attribute.
Callback
None (returns immediately)
Notes
Most of the string attributes have a maximum length defined by AW_MAX_ATTRIBUTE_LENGTH in Aw.h. This limit is currently 255 characters, or 256 bytes including the null character. There are a few attributes that can be longer than this (e.g. AW_BOTGRAM_TEXT). Their maximum lengths can vary up to 4095 characters (4096 bytes) depending on the attribute (e.g. AW_BOTGRAM_TEXT has a maximum length of 1000 characters).
See SDK Attributes for more information.
