错误:预期')'之前';' 代币

Question

我有这个愚蠢的小问题,我无法解决......

exer3.c: In function ‘shm_pipe_pipe’:
exer3.c:69:39: error: expected ‘)’ before ‘;’ token
exer3.c:69:39: error: too few arguments to function ‘shmget’
/usr/include/i386-linux-gnu/sys/shm.h:54:12: note: declared here

line的69周围环境:

pipes_array[i].m_key = 1;
key = i;

pipes_array[i].m_shmid = shmget(key, PIPE_SIZE, IPC_CREAT | IPC_EXCL | 0600); //69

if (pipes_array[i].m_shmid < 0) {
    perror("Error");
    return -1;
}

然后:

exer3.c: In function ‘shm_pipe_read’:
exer3.c:111:60: error: expected ‘)’ before ‘;’ token

line的111环境:

    current_bytes_to_read = total_bytes_to_read <= pipes_array[i].m_bytes_in_pipe ? total_bytes_to_read : pipes_array[i].m_bytes_in_pipe;

    //reading the information
    if ((pipes_array[i].m_roffset + current_bytes_to_read) < PIPE_SIZE) { //111
        memcpy(buf + offset, tbuffer + pipes_array[i].m_roffset, current_bytes_to_read);

那么:exer3.c:在函数'shm_pipe_write'中:exer3.c:153:41:错误:预期')'在';'之前 代币

line的153环境:

while (total_bytes_to_write != 0) {
    if (pipes_array[i].m_bytes_in_pipe == PIPE_SIZE) { //153


make: *** [exer3.o] Error 1

有人可以帮我吗？谢谢!

Answer 1

您的PIPE_SIZE宏可能如下所示:

#define PIPE_SIZE   100;

抛出分号(如果它们不存在则添加一些parens).
