How to read the configuration file from a C program in Linux

Share a Linux CProgramHow to read the configuration file

When your configuration file is like

 

Key1 = value1
# This is a comment
Key2 = value2

 

Type file,
It is really very simple and fast.
Assume that your configuration file name is/path/to/file/myconf.
Your C program is/path/to/file/myprog
Write an SH script. The script content is

 

 

./Path/to/file/myconf
/Path/to/file/myprog

 

 

Save the script and add the execution permission to the script.
Use this script to execute your program later. The configuration required by the program is put in the environment variable. You can use the getenv function (<stdlib. h>) to obtain the configuration.
Is it very simple? ^_^
