These darn incomplete types don't let me fill out the APR types. - -The APR developers acknowledge that most programs are not using APR, and -we don't expect them to migrate to using APR just because APR has been -released. So, we have provided a way for non-APR'ized programs to interact -very cleanly with APR. - -There are a set of functions, all documented in apr_portable.h, which allow -a programmer to either get a native type from an APR type, or to setup an -APR type from a native type. - -For example, if you are writing an add-on to another program that does not use -APR for file I/O, but you (in your infinite wisdom) want to use APR to make -sure your section is portable. Assume the program provides a type foo_t with -a file descriptor in it (fd). - -void function_using_apr(foo_t non_apr_struct, ap_pool_t *p) -{ - ap_file_t *apr_file = NULL; - - ap_put_os_file(&apr_file, &non_apr_struct->fd, p); - - ... -} - -There are portable functions for each APR incomplete type. They are all -called ap_put_os_foobar(), and they each take the same basic arguments, a -pointer to a pointer to the incomplete type (the last pointer in that list -should be NULL), a pointer to the native type, and a pool. Each of these can -be found in apr_portable.h. - -If you have to do the exact opposite (take an APR type and convert it to a -native type, there are functions for that too. For example: - -void function_not_using_apr(apr_file_t *apr_file) -{ - int unix_file_desc; - - ap_get_os_file(&unix_file_desc, apr_file); - - ... -} - -For each ap_put_os_foobar, there is a corresponding ap_get_os_file.
