虽然我知道有用于配置文件解析的库我已经尝试编写自己的实现。问题是我可以找到配置选项,但是当我尝试将它与我正在搜索的东西进行比较时,在分隔符失效之前比较字符串。我需要将它与我正在搜索的内容相媲美,因为我的程序允许像Test2和Test3这样的东西,因为它无法检查单词Test之前或之后是否有字符。比较总是失败,我无法弄清楚为什么。这是我的代码:
MAIN.C
#include <stdio.h>
#include <stdlib.h>
void Parser(char *CONFIG_FILE, int *P_VALUE, char *STRING_TO_LOOK_FOR);
int main(){
int VALUE;
Parser("config.txt", &VALUE, "Test");
printf("%d \n", VALUE);
}
Parser.c:
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
void Parser(char *CONFIG_FILE, int *P_VALUE, char *STRING_TO_LOOK_FOR){
FILE *FP=fopen(CONFIG_FILE,"a+");
char TMP[256]={0x0};
int i = 1;
while(FP!=NULL && fgets(TMP, sizeof(TMP), FP)!=NULL){ //Loop through every line
i=i+1; //Increment the line number
if (strstr(TMP, STRING_TO_LOOK_FOR)){ //Is the term im looking for in this line
char *NAME_OF_CONFIG_STR = strtok(TMP, "= "); //look for delimiter
char *STRVALUE = strtok(NULL, "= "); //Get everything past the delimiter
char *P_PTR;
char *pos;
if ((pos=strchr(NAME_OF_CONFIG_STR, '\n')) != NULL){ //attempt remove \n doesn't work
*pos = '\0';
}
if(strcmp(STRING_TO_LOOK_FOR, NAME_OF_CONFIG_STR) == 0){ //try to check the two are the same
*P_VALUE = strtol(STRVALUE, &P_PTR, 10); //Returns an integer to main of the value
}
}
}
if(FP != NULL){
fclose(FP);
}
}
的config.txt:
Test= 1234
Test2= 5678
Test3= 9012
感谢BLUEPIXY和他们创建的演示这个问题已经解决了。问题出在我忘记的gcc编译器选项-std = 99,这导致程序行为正常。
