STRTOIMAX(3P)                                       POSIX Programmer's Manual                                      STRTOIMAX(3P)



PROLOG
       This  manual  page is part of the POSIX Programmer's Manual.  The Linux implementation of this interface may differ (con-
       sult the corresponding Linux manual page for details of Linux behavior), or the  interface  may  not  be  implemented  on
       Linux.

NAME
       strtoimax, strtoumax - convert string to integer type

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 shall be equivalent to the strtol(), strtoll(), strtoul(), and strtoull() functions, except that the ini-
       tial portion of the string shall be converted to intmax_t and uintmax_t representation, respectively.

RETURN VALUE
       These functions shall return the converted value, if any.

       If no conversion could be performed, zero shall be returned.

       If the correct value is outside the range of representable values, {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall  be
       returned (according to the return type and sign of the value, if any), and errno shall be set to [ERANGE].

ERRORS
       These functions shall fail if:

       ERANGE The value to be returned is not representable.


       These functions may fail if:

       EINVAL The value of base is not supported.
