here is my starting code:

//open custom file
int fs_open_custom(struct fs_file *file, const char *name) {

//open log file
if(strncmp_url(name,”/log_file.txt”,13)>0)
{
file->data = “buffer_open_custom”;
file->len = 1000;
file->index = 0;
file->pextension = NULL;
file->is_custom_file = 1;

//0 if unable to open
return 1;
}
}

//read file and fill “buffer” step by step by “count” bytes amount
int fs_read_custom(struct fs_file *file, char *buffer, int count) {

int read = 0;
if (file->index < file->len)
{
read = 100;
file->is_custom_file = 1;
buffer = “buffer_read_custom”;
}
else
{
//end reached
read = FS_READ_EOF;
}
return read;
}

void fs_close_custom(struct fs_file *file){

//close file
//f_close(&fileOpen);

}

fs_open_custom works ok and the first part of the page is correctly loaded, then fs_read_custom is called 10 times before return FS_READ_EOF but only the first call appends to the buffer “buffer_read_custom” string, next calls append only part of “fsdata_custom.c” file. Any idea about this behavior? This is only a proof of concept example. I just need to test this code works correctly
