struct  etl_error_t
 An exception object. More...

Defines

#define ETL_ERR(expression)
 Check if the etl_error_t returned by expression is equal to ETL_SUCCESS.
#define ETL_SUCCESS   NULL
 Successful return value for a function that returns etl_error_t.
#define etl_error_create(err, msg)
 Return a new etl_error_t with underlying apr_status_t err and message msg.
#define etl_error_createf(err, fmt,)
 Return a new etl_error_t with underlying apr_status_t err and message created printf style with fmt and varargs.

Functions

etl_error_t * etl_error_create_impl (apr_status_t err, const char *msg, apr_uint32_t line, const char *file)
 The underlying function that implements etl_error_create.
etl_error_t * etl_error_createf_impl (apr_status_t err, apr_uint32_t line, const char *file, const char *fmt,...)
 The underlying function that implements etl_error_createf.
void etl_error_clear (etl_error_t *err)
 Destroy err.

Define Documentation

#define ETL_ERR (  expression   ) 
 

Value:

do {                \
          etl_error_t *etl__err = (expression); \
          if (etl__err)                         \
            return etl__err;                    \
        } while (0)
Check if the etl_error_t returned by expression is equal to ETL_SUCCESS.

If it is, do nothing, if not, then return it.
