Function Documentation
| int imDataTypeSize | ( | int | data_type | ) |
Returns the size in bytes of a specified numeric data type.
im.DataTypeSize(data_type: number) -> size: number [in Lua 5]
| const char* imDataTypeName | ( | int | data_type | ) |
Returns the numeric data type name given its identifier.
im.DataTypeName(data_type: number) -> name: string [in Lua 5]
| unsigned long imDataTypeIntMax | ( | int | data_type | ) |
Returns the maximum value of an integer data type. For floating point returns 0.
im.DataTypeIntMax(data_type: number) -> int_max: number [in Lua 5]
| long imDataTypeIntMin | ( | int | data_type | ) |
Returns the minimum value of an integer data type. For floating point returns 0.
im.DataTypeIntMin(data_type: number) -> int_min: number [in Lua 5]
