And nowhere is this more true than Borland Turbo C++, which has
several kinds of pointers, of differing sizes, due to 16-bit segment weirdness.

NAME
ltostr(), ultostr(), ltoa(), ultoa() - convert long integers to strings
SYNOPSIS
Obsolescent Interfaces
DESCRIPTION
Convert a signed long integer to the corresponding string
representation in the specified base. The argument base must be between 2 and 36, inclusive.
Convert an unsigned long integer to the corresponding string
representation in the specified base. The argument base must be between 2 and 36, inclusive.
Convert a signed long integer to the corresponding base 10
string representation, returning a pointer to the result.
Convert an unsigned long integer to the corresponding base 10
string representation, returning a pointer to the result.
These functions are smaller and faster than using for simple conversions (see printf(3S)).
Obsolescent Interfaces
convert long integers to strings.
ERRORS
If the value of base is not between 2 and 36, and return NULL and set the external variable to ERANGE.
WARNINGS
The return values for and point to data whose content is overwritten by subsequent calls to these functions by the same thread.
and are obsolescent interface supported only for compatibility with existing DCE applications. New multi-threaded applications should use
