Try to create a NFS Cleint for Dos:

[chrisx78]

Hello,
i try to create and compile a NFS cleint and i have no success. I ask google and near everithing what can genereate code but there is no right help. So maybe here can help me somewhere to fix the issue or can explain me what is wrong:

OW default C standard is C89 that you cannot mix data declaration with code.
declaration can be only on block begining before code statements.
You need a litle rearange your code by moving line

    char __far *filename_far = MK_FP(r.w.ds, r.w.dx);
    char filename[256];
    _fmemcpy(filename, filename_far, _fstrlen(filename_far) + 1);  // Use _fstrlen for far pointer         <<- this line
    char file_handle[64];
    unsigned char handle_len;
    static char read_buffer[512];
    static unsigned long file_offset = 0;

    if (nfs_mounted && filename[0] == mapped_drive && filename[1] == ':') {

after data declaration

    char __far *filename_far = MK_FP(r.w.ds, r.w.dx);
    char filename[256];
    char file_handle[64];
    unsigned char handle_len;
    static char read_buffer[512];
    static unsigned long file_offset = 0;

    _fmemcpy(filename, filename_far, _fstrlen(filename_far) + 1);  // Use _fstrlen for far pointer    <<- new position
    if (nfs_mounted && filename[0] == mapped_drive && filename[1] == ':') {

Or if you want to use mixed declaration and code statements than it is enabled by C99 standard.
For C99 standard you need to add -za99 compiler option.

thank you so much, thats it. 👍
I have try to fix the issue several Hours. on several Days
