88 A large part of the code here deals with emulating glibc's reentrant
89 locale API on non-GNU systems. The emulation is a bit "brute-force":
90 Whenever a `-locale<?' procedure is passed a locale object, then:
92 1. The `scm_i_locale_mutex' is locked.
93 2. A series of `setlocale ()' call is performed to store the current
94 locale for each category in an `scm_t_locale' object.
95 3. A series of `setlocale ()' call is made to install each of the locale
96 categories of each of the base locales of each locale object,
97 recursively, starting from the last locale object of the chain.
98 4. The settings captured in step (2) are restored.
99 5. The `scm_i_locale_mutex' is released.
101 Hopefully, the X/Open standard will eventually make this hack useless.
103 Note: We don't wrap glibc's `uselocale ()' call because it sets the locale
104 of the current _thread_ (unlike `setlocale ()') and doing so would require
105 maintaining per-thread locale information on non-GNU systems and always
106 re-installing this locale upon locale-dependent calls. */
