This header defines the primative LAL datatypes. These datatypes are: CHAR, INT2, INT4, INT8 (signed integer types); UCHAR, UINT2 UINT4, UINT8 (unsigned integer types); REAL4, REAL8 (single- and double-precision floating point types); and COMPLEX8 and COMPLEX16 (single- and double-precision floating point complex types). Note that the complex types are implemented as structures. This is because LAL conforms to the C89 standard rather than the C99 standard. The non-complex datatypes are known as atomic datatypes: these may be passed directly to functions or used as the return value of XLAL functions.

The number in the name of each of these types (other than CHAR and UCHAR) is the number of 8-bit bytes that the datatype occupies. E.g., INT4 is a four-byte integer. In C99 it would be called int32_t. While the size of types such as int and long int are platform dependent, the sizes of INT4 and INT8 is always 4- and 8-bytes respectively (platform independent). REAL4 and REAL8 are always type float and double but LAL is only supported on platforms in which these types conform to the IEEE 754 standard.

This documentation shows how the datatypes are defined on today's most common (32-bit) platform. Be careful in particular about the integer type INT8. On 64-bit platforms it will usually be equivalent to type long int rather than type long long int.
