|

|
|
* Basic data type definitions. These definitions allow GKlib to separate
|
||
|
|
* the following elemental types:
|
||
|
|
* - loop iterator variables, which are set to size_t
|
||
|
|
* - signed and unsigned int variables that can be set to any # of bits
|
||
|
|
* - signed and unsigned long variables that can be set to any # of bits
|
||
|
|
* - real variables, which can be set to single or double precision.
