NAME
ltostr(), ultostr(), ltoa(), ultoa() — convert long integers to strings
SYNOPSIS
#include <stdlib.h>
char *ltostr(long n, int base);
char *ultostr(unsigned long n, int base);
char *ltoa(long n);
char *ultoa(unsigned long n);
Obsolescent Interfaces
int ltostr_r(long n, int base, char *buffer, int buflen);
int ultostr_r(unsigned long n, int base, char *buffer, int buflen);
int ltoa_r(long n, char *buffer, int buflen);
int ultoa_r(unsigned long n, char *buffer, int buflen);
DESCRIPTION
- ltostr()
Convert a signed long integer to the corresponding string
representation in the specified base.
The argument
base
must be between 2 and 36, inclusive.
- ultostr()
Convert an unsigned long integer to the corresponding string
representation in the specified base.
The argument
base
must be between 2 and 36, inclusive.
- ltoa()
Convert a signed long integer to the corresponding base 10
string representation, returning a pointer to the result.
- ultoa()
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
sprintf()
for simple conversions (see
printf(3S)).
Obsolescent Interfaces
ltostr_r(),
ultostr_r(),
ltoa_r(),
ultoa_r()
convert long integers to strings.
ERRORS
If the value of
base
is not between 2 and 36,
ltostr()
and
ultostr()
return NULL and set the external variable
errno
to ERANGE.
WARNINGS
The return values for
ltostr(),
ultostr(),
ltoa()
and
ultoa()
point to data
whose content is overwritten by subsequent calls to these functions
by the same thread.
ltostr_r(),
ultostr_r(),
ltoa_r()
and
ultoa_r()
are obsolescent interface supported only for compatibility with
existing DCE applications. New multi-threaded applications should use
ltostr(),
ultostr(),
ltoa()
and
ultoa().
AUTHOR
ltostr(),
ultostr(),
ltoa(),
and
ultoa()
were developed by HP.
