linux线程传参数

linux线程传参数，以char*为例子

#include <stdio.h>#include <stdlib.h>#include <pthread.h>void* screenData( void *filename );int main(int argc, char *argv[]){pthread_t thread;char *filename = "some_directory/some_other/";/*your code was passing a pthread_t** instead of pthread_t* */if( pthread_create( &thread, NULL, screenData, (void*)filename)  != 0){return 0;}pthread_join( thread, NULL);return 0;}void* screenData( void *filename ){char* name;if(filename){name = (char*)filename;/*check your format specifier*/printf("In SD=%s, %x\n", name, name );}return 0;}
