소켓에서 데이터를 읽고 fwrite로 fuile에 쓰기를 원하지만 예외가 계속 발생합니다. 내 코드 :vxworks의 ftp 소켓에서 읽음
MyFile = fopen ("flash:/ngfm.bin","wb");
if (MyFile != NULL) {
while ((nBytes = read (dataSock, buf, sizeof (buf))) > 0) {
ByteCount++;
if (ByteCount %10)
printf(".");
if (ByteCount %100)
printf("\n");
fwrite(buf, sizeof(buf), nBytes, MyFile);
}
printf("%d Bytes written to flash:/ngfm.bin!\n", ByteCount);
fclose(MyFile);
}
close (dataSock);

내 장치 플래시에 : 존재하고 쓰기입니다! 쉘에서 다음을 수행했습니다 :
JPAX-DP> mf = fopen("flash:/test","w")
New symbol "mf" added to kernel symbol table.
mf = 0x26e75e90: value = 636346784 = 0x25ede1a0
JPAX-DP> fputs("TEST",mf)
value = 0 = 0x0
JPAX-DP> fclose(mf)
value = 0 = 0x0
JPAX-DP> ls("flash:/")
