Function Documentation

int ap_graceful_stop_signalled (  void   )

predicate indicating if a graceful stop has been requested ... used by the connection loop Returns: 1 if a graceful stop has been requested, 0 otherwise int ap_graceful_stop_signalled(*void)

apr_status_t ap_mpm_query (  int  query_code, int *  result )

Query a property of the current MPM. Parameters: query_code  One of APM_MPMQ_* result  A location to place the result of the query Returns: APR_SUCCESS or APR_ENOTIMPL int ap_mpm_query(int query_code, int *result)

int ap_mpm_run (  apr_pool_t *  pconf, apr_pool_t *  plog, server_rec *  server_conf )

This is the function that MPMs must create. This function is responsible for controlling the parent and child processes. It will run until a restart/shutdown is indicated. Parameters: pconf  the configuration pool, reset before the config file is read plog  the log pool, reset after the config file is read server_conf  the global server config. Returns: 1 for shutdown 0 otherwise. int ap_mpm_run(apr_pool_t *pconf, apr_pool_t *plog, server_rec *server_conf)

apr_status_t ap_os_create_privileged_process (  const request_rec *  r, apr_proc_t *  newproc, const char *  progname, const char *const *  args, const char *const *  env, apr_procattr_t *  attr, apr_pool_t *  p )

Spawn a process with privileges that another module has requested Parameters: r  The request_rec of the current request newproc  The resulting process handle. progname  The program to run const_args  the arguments to pass to the new program. The first one should be the program name. env  The new environment apr_table_t for the new process. This should be a list of NULL-terminated strings. attr  the procattr we should use to determine how to create the new process p  The pool to use.
