            Bug ID: 17651
           Summary: Expose thread-safe timezone API
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: libc
          Assignee: unassigned at sourceware dot org
          Reporter: maxim.yegorushkin at gmail dot com
                CC: drepper.fsp at gmail dot com

Upstream tz project exposes the functions required for easy and thread-safe
timezone conversions, see
https://github.com/eggert/tz/blob/master/private.h#L409

    /*
    ** Define functions that are ABI compatible with NetBSD but have
    ** better prototypes.  NetBSD 6.1.4 defines a pointer type timezone_t
    ** and labors under the misconception that 'const timezone_t' is a
    ** pointer to a constant.  This use of 'const' is ineffective, so it
    ** is not done here.  What we call 'struct state' NetBSD calls
    ** 'struct __state', but this is a private name so it doesn't matter.
    */
    #if NETBSD_INSPIRED

    typedef struct state *timezone_t;
    struct tm *localtime_rz(timezone_t restrict, time_t const* restrict, struct
tm* restrict);
    time_t mktime_z(timezone_t restrict, struct tm *restrict);
    timezone_t tzalloc(char const *);
    void tzfree(timezone_t);

    /* ... */
    #endif

Would it be possible to expose these NETBSD_INSPIRED 4 functions in glibc?

--- Comment #1 from joseph at codesourcery dot com <joseph at codesourcery dot com> ---
Please propose new APIs on libc-alpha, not in Bugzilla (and expect to take 
a lead in driving the discussion to consensus, and in producing a complete 
implementation, including documentation and testcases, if a consensus is 
reached that the APIs are appropriate to add to glibc).
