Question

I wrote a simple test application to log something in a log file. I am using linux mint and after the application executes I try to view the log using this command: <

In addition to the accepted answer, it is useful to know the following ...

Each of those functions should have manual pages associated with them.

If you run man -k syslog (a keyword search of man pages) you will get a list of man pages that refer to, or are about syslog

$ man -k syslog
logger (1)           - a shell command interface to the syslog(3) system l...
rsyslog.conf (5)     - rsyslogd(8) configuration file
rsyslogd (8)         - reliable and extended syslogd
syslog (2)           - read and/or clear kernel message ring buffer; set c...
syslog (3)           - send messages to the system logger
vsyslog (3)          - send messages to the system logger

You need to understand the manual sections in order to delve further.

Here's an excerpt from the man page for man, that explains man page sections :

The table below shows the section numbers of the manual followed  by
the types of pages they contain.

   1   Executable programs or shell commands
   2   System calls (functions provided by the kernel)
   3   Library calls (functions within program libraries)
   4   Special files (usually found in /dev)
   5   File formats and conventions eg /etc/passwd
   6   Games
   7   Miscellaneous  (including  macro  packages and conven‐
       tions), e.g. man(7), groff(7)
   8   System administration commands (usually only for root)
   9   Kernel routines [Non standard]

To read the above run

$man man 

So, if you run man 3 syslog you get a full manual page for the syslog function that you called in your code.

SYSLOG(3)                Linux Programmer's Manual                SYSLOG(3)

Not a direct answer but hopefully you will find this useful.
