Currently the following units are understood: * If no unit is contained in the given timeout parameter the default_time_unit * @param timeout_parameter The string containing the timeout parameter. * @param timeout The timeout value to be returned. * @param default_time_unit The default time unit to use if none is specified * @return Status value indicating whether the parsing was successful or not. /* Misc system hackery */ * Given the name of an object in the file system determine if it is a directory * @param p The pool to allocate from * @param name The name of the object to check * @return 1 if it is a directory, 0 otherwise * Given the name of an object in the file system determine if it is a directory - this version is symlink aware * @param p The pool to allocate from * @param name The name of the object to check * @return 1 if it is a directory, 0 otherwise * Determine the local host name for the current machine * @param p The pool to allocate from * @return A copy of the local host name * Log an assertion to the error log * @param szExp The assertion that failed * @param szFile The file the assertion is in * @param nLine The line the assertion is defined on * @internal Internal Assert function * Redefine assert() to something more useful for an Apache... * Use ap_assert() if the condition should always be checked. * Use AP_DEBUG_ASSERT() if the condition should only be checked when AP_DEBUG * @defgroup stopsignal Flags which indicate places where the sever should stop for debugging. * A set of flags which indicate places where the server should raise(SIGSTOP). * This is useful for debugging, because you can then attach to that process * with gdb and continue.
