获得当前运行进程的进程名

linux下，获得当前运行进程的进程名及其路径。

 

放在这里mark一下。

#include <limits.h>#include <stdio.h>#include <string.h>#include <unistd.h>size_t get_executable_path (char* buffer, size_t len){ char* path_end; if (readlink (“/proc/self/exe”, buffer, len) <= 0) return -1; path_end = strrchr (buffer, ‘/’); if (path_end == NULL) return -1; ++path_end; *path_end = ‘/0’; return (size_t) (path_end - buffer);}int main (){ char path[PATH_MAX]; get_executable_path (path, sizeof (path)); printf (“this program is in the directory %s/n”, path); return 0;}
