NAME

       qb_log_from_external_source  -  This  function  is  to  import logs from other code (like libraries) that
       provide a callback with their logs.

SYNOPSIS

       #include <qb/qblog.h>

       void qb_log_from_external_source(
           const char   *function,  /* originating function name */
           const char   *filename,  /* originating filename */
           const char   *format,    /* format string */
           uint8_t       priority,  /* this takes syslog priorities. */
           uint32_t      lineno,    /* file line number */
           /*
            * this is a uint32_t that you can use with
            * qb_log_tags_stringify_fn_set() to "tag" a log message with a feature or sub-system then you can use
            * "%g" in the format specifer to print it out.
            */
           uint32_t      tags,
           ...
       );

DESCRIPTION

NOTE

       the  performance  of  this  will  not  impress  you,  as  the  filtering is done on each log message, not
       beforehand. So try doing basic pre-filtering.
