(description
|
||||||
|
"uthash implements a hash table and a few other basic data structures
|
||||||
|
as C preprocessor macros. It aims to be minimalistic and efficient: it's
|
||||||
|
around 1,000 lines of code which, being macros, inline automatically.
|
||||||
|
|
||||||
|
Unlike function calls with fixed prototypes, macros operate on untyped
|
||||||
|
arguments. Thus, they are able to work with any type of structure and key.
|
||||||
|
Any C structure can be stored in a hash table by adding @code{UT_hash_handle}
|
||||||
|
to the structure and choosing one or more fields to act as the key.")
