about _int_disable

I find _int_disable in MQX seems not disable interrupt actually. see the following codes:

 

_int_disable();

for(i=0;i<3;i++){

file = fopen("a:init.txt","a+");

if(file!=NULL)

break;

}

if(i==3){

return -1;

}

fseek(file,0,IO_SEEK_SET);

_bsp_serve_wdog();

i = write(file,(char*)&board_info,sizeof(board_info));

 

...

fclose(file);

_int_enable();

return 0;

 

I find other tasks can get cpu running after _int_disable, and if another task also call above codes, the synchronization trouble occur!
