QB_LOG_CTL2(3) libqb Programmer's Manual QB_LOG_CTL2(3)

qb_log_ctl2 - Extension of main logging control function accepting also strings.

#include <qb/qblog.h>

int32_t qb_log_ctl2(
    int32_t            target,
    enum qb_log_conf   conf_type,
    qb_log_ctl2_arg_t  arg
);

target QB_LOG_SYSLOG, QB_LOG_STDERR or result from

conf_type configuration directive ("what to configure") that accepts either

arg the new value for a state-changing configuration directive, ignored otherwise; for QB_LOG_CONF_IDENT, 's' member as new identifier to openlog(), for all qb_log_ctl-compatible ones, 'i32' member is assumed (although a preferred way is to use that original function directly as it allows for more type safety) 


struct qb_log_ctl2_arg_t {
    int32_t       i32;
    const char   *s;
};


enum qb_log_conf {
      QB_LOG_CONF_ENABLED;
      QB_LOG_CONF_FACILITY;
      QB_LOG_CONF_DEBUG;
      QB_LOG_CONF_SIZE;
      QB_LOG_CONF_THREADED;
      QB_LOG_CONF_PRIORITY_BUMP;
      QB_LOG_CONF_STATE_GET;
      QB_LOG_CONF_FILE_SYNC;
      QB_LOG_CONF_EXTENDED;
      QB_LOG_CONF_IDENT;
      QB_LOG_CONF_MAX_LINE_LEN;
      QB_LOG_CONF_ELLIPSIS;
      QB_LOG_CONF_USE_JOURNAL;
};

You can use QB_LOG_CTL2_I32 and QB_LOG_CTL2_S macros for a convenient on-the-fly construction of the object to be passed as an arg argument.
