NAME

6       strtoimax, strtoumax - convert string to integer
7

LIBRARY

9       Standard C library (libc, -lc)
10

SYNOPSIS

12       #include <inttypes.h>
13
14       intmax_t strtoimax(const char *restrict nptr, char **restrict endptr,
15                          int base);
16       uintmax_t strtoumax(const char *restrict nptr, char **restrict endptr,
17                          int base);
18

DESCRIPTION

20       These  functions  are  just  like strtol(3) and strtoul(3), except that
21       they return a value of type intmax_t and uintmax_t, respectively.
22

RETURN VALUE

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