SYNOPSIS

11
12       void qb_log_format_set(
13           int32_t       t,
14           const char   *format
15       );

DESCRIPTION

18       %n FUNCTION NAME
19
20       %f FILENAME
21
22       %l FILELINE
23
24       %p PRIORITY
25
26       %t TIMESTAMP
27
28       %T TIMESTAMP with milliseconds
29
30       %b BUFFER
31
32       %g TAGS
33
34       %N name (passed into qb_log_init)
35
36       %P PID
37
38       %H hostname
39
40       Any number between % and character specify field length to pad or chop.
41

NOTE

43       Some of the fields are immediately evaluated and remembered for perfor‐
44       mance reasons, so whenlog messages carry PIDs (not  the  default)  this
45       function needs to be reinvoked following fork (clone) in the respective
46       children. When already linking with libpthread, pthread_atfork callback
47       registration could be useful.
