linux获取当前进程名

linux系统中有个符号链接：/proc/self/exe 它代表当前程序；可以采用readlink来获取；

#include <unistd.h>
#include <stdio.h>

int main(int argc , char* argv[])
{
	char aucPathBuf[1024] = {0};
	char *pcName	= NULL;
	if( readlink("/proc/self/exe", aucPathBuf,1024) <=0 )
	{
			return -1;
	}
 
	char *pcName = strrchr( aucPathBuf, '/' ); 
	if ( NULL != pcName )
	{
			printf("pcName：%s\n", ++pcName);
			printf("aucPathBuf：%s\n", aucPathBuf);
	}
	else
	{
		return -1;
	}
	return 0;
}
