strtoimax(3)            Library Functions Manual            strtoimax(3)

NAME         top

       strtoimax, strtoumax - convert string to integer

LIBRARY         top

       Standard C library (libc, -lc)

SYNOPSIS         top

       #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         top

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

RETURN VALUE         top

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