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);

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 sprintf(3C)).

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 point to static data whose content is overwritten by each call.
