2.6 long long Data Type

When you compile with -xc99=none, the Oracle Solaris Studio C compiler includes the data types long long and unsigned long long, which are similar to the data type long. The long long data type stores 64 bits of information; long stores 32 bits of information when compiling with -m32. The long data type stores 64 bits when compiling with -m64. The long long data type is not available in -Xc mode (a warning is issued).

2.6.1 Printing long long Data Types

To print or scan long long data types, prefix the conversion specifier with the letters ll. For example, to print llvar, a variable of long long data type, in signed decimal format, use:

printf("%lld\n", llvar);

2.6.2 Usual Arithmetic Conversions

Some binary operators convert the types of their operands to yield a common type, which is also the type of the result. These operators are the usual arithmetic conversions:
