Hello,
I initialize the io-driver for memory with this code. That works well:
uint8_t memory [4000]; uint32_t mem_init (void){ MQX_FILE_PTR drive_p = NULL; _mqx_uint error_code = 0; if ( (error_code = _io_mem_install(NAME_OF_FILE, memory, sizeof(memory))) == MQX_OUT_OF_MEMORY) { printf("could not install drive\n"); return 1; } //!____Open_the_drive______________________________________________________ drive_p = _io_fopen( NAME_OF_FILE, "r"); if (drive_p == NULL ) { printf("unable to open %s\n", NAME_OF_FILE); return 1; } //!___close________________________________________________________________ _io_fclose(drive_p); return 0;}
After that, I open again with:
pDataFile = fopen(NAME_OF_FILE, "w+");
and write some lines with:
fprintf(pDataFile, "%s\n", buffer);
Until this point everything works well. Now I read out all lines until the function “_io_fgetline()” receive “IO_EOF”. But I get much more (empty) lines as I have written before.
Why the driver does not set the EOF automatically?
Can I set explicit the “End Of File”?
Thank you for response.
