stoi, numtos - convert between an integer and a decimal string
#include <sys/ddi.h>
int stoi(char **str);
void numtos(unsigned long num, char *s);
illumos DDI specific (illumos DDI).
str
Pointer to a character string to be converted.
num
Decimal number to be converted to a character string.
s
Character buffer to hold converted decimal number.
stoi()
The stoi() function returns the integer value of a string of decimal
numeric characters beginning at **str. No overflow checking is done.
*str is updated to point at the last character examined.
numtos()
The numtos() function converts a long into a null-terminated
character string. No bounds checking is done. The caller must ensure
there is enough space to hold the result.
The stoi() function returns the integer value of the string str.
The stoi() function can be called from user, interrupt, or kernel
context.
Writing Device Drivers
The stoi() function handles only positive integers; it does not
handle leading minus signs.

The numtos() function converts a long into a null-terminated
character string. No bounds checking is done. The caller must ensure
there is enough space to hold the result.
RETURN VALUES
The stoi() function returns the integer value of the string str.
