现在在做一个WIFI API相关的库,这样就可以让其他的人管理WIFI.
在调用API的时候要回复SHELL打印的信息,比如说搜索热点,而且不在SHELL中打印出来。然后把信息返回给调用API的程序。
#include <stdio.h> #include <stdlib.h> int main( int argc, char *argv[] ) { FILE *fp; char path[1035]; /* Open the command for reading. */ fp = popen("/bin/ls /etc/", "r"); if (fp == NULL) { printf("Failed to run command\n" ); exit(1); } /* Read the output a line at a time - output it. */ while (fgets(path, sizeof(path), fp) != NULL) { printf("%s", path); } /* close */ pclose(fp); return 0; }
You want the "popen" function. Here‘s an example of running the command "ls /etc" and outputing to the console.
