ASSOCIATED | Determines whether a the first pointer argument and the second (optional) pointer argument are associated. | |
BIT_SIZE | Returns the number of bits in an integer type. | |
CACHESIZE1 | Returns the size of a level of the memory cache. | |
COMMAND_ARGUMENT_COUNT | Returns the number of command arguments. | |
DIGITS | Returns number of significant digits for data of the same type as the argument. | |
EOF | Determines whether a file is at or beyond the end-of-file record. | |
EPSILON | Returns the smallest positive number that when added to one produces a number greater than one for data of the same type as the argument. | |
