C读取配置文件

配置文件一项一行，中间用分号或者空格隔开，如：

ip :192.168.1.1
port: 80

 

程序如下：

#include <stdio.h>#include <string.h>#define MAXLENGTH 64#define MAXITEM 32int parseLine(char * line){char * devision = " /t/n/r";char * p = NULL;//char test[] = "if (key == 83) return 55;";if (strlen(line) > MAXLENGTH){printf("len=%d", strlen(line));return -1;}p = strtok(line, devision);//printf("%s",p);if (p != NULL){printf("str=%s", p);//return -1;}while(p = strtok(NULL, devision)){printf("next=%s/n",p);}return 0;}int getKeyValue(char *line, char *key, char*value){char * devision = " /t/n/r ;:";char * p = NULL;int items = 0;if (strlen(line) > MAXLENGTH){printf("len=%d", strlen(line));return -1;}p = strtok(line, devision);//printf("%s",p);if (p != NULL){//printf("str=%s", p);strcpy(key,p);items++;//return -1;}while(p = strtok(NULL, devision)){//printf("next=%s/n",p);if (items>1)//in this function , just one configbreak;strcpy(value,p);items++;}return 0;}int main(int argc, char **argv){char * configfile = "local.config";char line[MAXLENGTH] = {0};int lines = 0;char key[MAXITEM]={0},value[MAXITEM]={0};FILE * fp = fopen(configfile,"r");if (NULL == fp){printf("null files/n");return 0;}while (fgets(line, MAXLENGTH-1, fp) != NULL){lines++;//printf("%d:%s",lines,line);if (-1 != getKeyValue(line,key,value))printf("%s: %s/n",key,value);}return 0;}
