我有一個代碼,它將讀取一個csv文件並將數據保存在緩衝區中。但我得到分段錯誤核心轉儲作爲狀態錯誤。c中的分段錯誤(core dump)
的CSV文件的內容是
TimeStamp BlockSeqNum SeqNum X-axis Y-axis Z-axis
4294967295 0 0 27 20 -4
4294967295 0 1 48 11 -13

4294967295 0 15 -24 30 51
4294967295 0 16 -18 39 -45
我的代碼讀取和解析該文件是
#include<stdio.h>
#include<stdlib.h>
struct pattern_buffer { //structure to store the contents of csv files
unsigned int x[1024];
unsigned int y[1024];
unsigned int z[1024];
}Data_buffer;
int main(void)
{
char buffer[1024];
char *record,*line;
int x1=0,y1=0,z1=0,linecount=0; //linecount is used to check weather 1024 rows have been read or not
int n=0;
FILE *fstream = fopen("files.csv","r");
if(fstream == NULL) //check file
{
printf("\n inside .so \n unable to open csv files \n");
return 0;
}
printf("\n Sensor values are \n");
line=fgets(buffer,sizeof(buffer),fstream); //skip first line (weather it will skip the first line
while((line=fgets(buffer,sizeof(buffer),fstream))!=NULL && linecount<1024)
{
record=strtok(line,","); //skip first column
while(record!= NULL)
{
//record=strtok(NULL,","); //skip second column
record=strtok(NULL,","); //skip third column
record=strtok(NULL,","); //get x axis
Data_buffer.x[x1++]=atoi(record);
record=strtok(NULL,","); //get y axis
Data_buffer.y[y1++]=atoi(record);
//record=strtok(NULL,","); //get z axis
Data_buffer.z[z1++]=atoi(record);
}
linecount++;
}
return -1;
}
所以,請註明我度過我的邏輯是跳過第一線和讀取正確csv值。
注意:CSV示例中沒有逗號。 '-4'對於'unsigned int'不是一個有效的值。 – wildplasser
其實它並不是csv文件的副本。它有逗號,沒有顯示 –
我已經使用了現在已經簽名的int,但仍然無法出去放,相同的錯誤 –
