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 (consult 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
       The functionality described on this reference page is aligned with  the
       ISO C  standard.  Any  conflict between the requirements described here
       and the ISO C standard is unintentional. This  volume  of  POSIX.1-2008
       defers to the ISO C standard.
       These  functions  shall  be equivalent to the strtol(), strtoll(), str-
       toul(), and strtoull() functions, except that the  initial  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  and  errno
       may be set to [EINVAL].
       If  the  value  of base is not supported, 0 shall be returned and errno
       shall be set to [EINVAL].
       If the correct value is outside  the  range  of  representable  values,
       {INTMAX_MAX}, {INTMAX_MIN}, or {UINTMAX_MAX} shall be returned (accord-
       ing to the return type and sign of the value, if any), and errno  shall
       be set to [ERANGE].
ERRORS
       These functions shall fail if:
       EINVAL The value of base is not supported.
       ERANGE The value to be returned is not representable.
       These functions may fail if:
       EINVAL No conversion could be performed.
       The following sections are informative.
EXAMPLES
       None.
APPLICATION USAGE
       Since  the  value of *endptr is unspecified if the value of base is not
       supported, applications should either ensure that base has a  supported
       value (0 or between 2 and 36) before the call, or check for an [EINVAL]
       error before examining *endptr.
RATIONALE
       None.
FUTURE DIRECTIONS
       None.
