还记得Windows使用的配置文件吗?看看boot.ini文件内容
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Windows Server 2003, Standard" /fastdetect /NoExecute=OptOut
C:\wubildr.mbr = "Ubuntu"
Linux中提供了功能更为强大的KeyValue数据格式,可用于生成更为灵活的配置文件,下面的代码实例演示了使用GKeyFile生成配置文件,本例代码使用了字符串,布尔值,整型值,双精度值和字符串列表等数据类型,将其写入配置文件中。
#include
#include
int main(int argc,char** argv){
GKeyFile* config = g_key_file_new();
gsize length = 0;
#define STARUP "STARTUP"
#define PATH "PATH"
g_key_file_set_value(config,STARUP,"x","300");
g_key_file_set_string(config,STARUP,"y","600");
g_key_file_set_boolean(config,STARUP,"center",TRUE);
GTimeVal now;
g_get_current_time(&now);
g_key_file_set_integer(config,STARUP,"timestamp",now.tv_sec);
GRand* r = g_rand_new();
g_key_file_set_double(config,STARUP,"random",g_rand_double(r));
const char* const search_path[] = { "/bin","/sbin","/usr/bin","/usr/local/bin","/home/jcodeer/bin"};
g_key_file_set_string_list(config,PATH,"bin_path",search_path,5);
gchar* content = g_key_file_to_data(config,&length,NULL);
g_print("%s\n",content);
FILE* fp = fopen("./019.ini","w");
if(fp == NULL) return -1;
fwrite(content,1,length,fp);
fclose(fp);
#undef STARUP
#undef PATH
g_key_file_free(config);
return 0;
}
生成的INI配置文件内容为:
[STARTUP]
x=300
y=600
center=true
timestamp=1314432584
random=0.78204092288815774
[PATH]
bin_path=/bin;/sbin;/usr/bin;/usr/local/bin;/home/jcodeer/bin;
