pub unsafe extern "C" fn ruby_setenv(
key: *const c_char,
val: *const c_char,
)Expand description
Sets an environment variable. In case of POSIX this is a wrapper of
setenv(3). But there are systems which lack one. We try hard emulating.
ยง@param[in] key An environment variable.
@param[in] val A value to be associated with key, or 0.
@exception rb_eSystemCallError setenv(3) failed for some reason.
@post Environment variable key is created if necessary. Its value
is updated to be val.
