strtoimax, strtoumax - convert string to integer
LIBRARY
Standard C library (libc, -lc)
SYNOPSIS
#include <inttypes.h>
intmax_t strtoimax(const char *restrict nptr, char **restrict endptr,
int base);
uintmax_t strtoumax(const char *restrict nptr, char **restrict endptr,
int base);
DESCRIPTION
These functions are just like strtol(3) and strtoul(3), except that they
return a value of type intmax_t and uintmax_t, respectively.

On success, the converted value is returned. If nothing was found to
convert, zero is returned. On overflow or underflow INTMAX_MAX or INT-
MAX_MIN or UINTMAX_MAX is returned, and errno is set to ERANGE.
