Converts between 3-byte integers and long integers.
Standard C Library (libc.a)
void l3tol ( LongPointer, CharacterPointer, Number)
long *LongPointer;
char *CharacterPointer;
int Number;
void ltol3 (CharacterPointer, LongPointer, Number) char *CharacterPointer; long *LongPointer; int Number;
The l3tol subroutine converts a list of the number of 3-byte integers specified by the Number parameter packed into a character string pointed to by the CharacterPointer parameter into a list of long integers pointed to by the LongPointer parameter.
The ltol3 subroutine performs the reverse conversion, from long integers (the LongPointer parameter) to 3-byte integers (the CharacterPointer parameter).
These functions are useful for file system maintenance where the block numbers are 3 bytes long.
| LongPointer | Specifies the address of a list of long integers. |
| CharacterPointer | Specifies the address of a list of 3-byte integers. |
| Number | Specifies the number of list elements to convert. |
