§ 解释 函数名: fdopen 功 能: 把流与一个文件句柄相接 用 法: FILE *fdopen(int handle, char *type); § 程序例 #include <sys\\stat.h> #include <stdio.h> #include <fcntl.h> #include <io.h> int main(void) { int handle; FILE *stream; /* open a file */ handle = open("DUMMY.FIL", O_CREAT, S_IREAD | S_IWRITE); /* now turn the handle into a stream */ stream = fdopen(handle, "w"); if (stream == NULL) printf("fdopen failed\"); else { fprintf(stream, "Hello world\"); fclose(stream); } return 0; } |
