    SD Card : Seek and modify a character

    chetan.ke

       I found an SD card component to go with PSoC 4 here : http://www.element14.com/community/docs/DOC-63798/l/project-50--sd-card-example-psoc-4-pioneer-kit-community

         

      According to the example given, there is an option to seek (set an offset) and read a character. But is there a command to seek and modify ?? uchar SDCard_fputc(uchar Data, uchar Fptr), i think appends a character. Tell me a function(s) to do something as specific as this : open a file, change the 14th character to 'A' . Thanks a lot.
