"Getconf retrieves NAME=VALUE pairs from a configuration file through a C program." - 14 words.
Getconf is a C program that offers the ability to retrieve NAME=VALUE pairs from a configuration file. The program is equipped with a sample code that includes "getconf.h," as well as , , and .
The main function of this program is to retrieve a configuration file (in this case, "getconf_test.conf") and retrieve the desired variables and their values - shown in the sample code as "struct config c," "char *vars[MAX_LINES]," and "char *vals[MAX_LINES]." The program then proceeds to open the configuration file and store it in the 'lines' variable.
If the program fails to retrieve the configuration file, 'lines' will be less than zero, resulting in an error message informing the user that the configuration file could not be read. The program then exits with a failure code.
Once the configuration file has been successfully read, the 'get_config' function is used to retrieve the values in the configuration file. The program then performs a loop that retrieves the values for each variable defined in the configuration file.
In this loop, file values are allocated to the 'vars' and 'vals' variables using the "malloc" and "strcpy" functions. Additionally, the "printf" statement is used to display the retrieved variable and value information.
Lastly, the program concludes by cleaning up the memory that was allocated for the 'vars' and 'vals' variables by using the "free" function.
Overall, Getconf is an efficient program that can effectively extract configuration file information for various applications.
