M_Open_File_Append (); does not work.

[picluigi]

This is my code:

#include <built_in.h>

char
FAT_ERROR[20] = "FAT16 not found",
file_contents[50] = "XX MMC/SD FAT16 library by Luigi Rieckert\n";
char cont;
char
filename[14] = "MIKRO00xTXT"; // File names
unsigned short
tmp, caracter, loop, loop2;
unsigned long
i, size;

void I_Write_Str(char *ostr) {
unsigned short i;

i = 0;
while (ostr) {
USART_Write(ostr[i++]);
}
USART_Write(0x0A);
}//~
//M-M-M--------- Creates new file and writes some data to it
void M_Create_New_File() {
filename[7] = 'A';
Mmc_Fat_Assign(&filename, 1); // Will not find file and then create file
Mmc_Fat_Rewrite(); // To clear file and start with new data
Mmc_Fat_Write(file_contents, 42); // write data to the assigned file
}
//M-M-M--------- Opens an existing file and appends data to it
// (and alters the date/time stamp)
void M_Open_File_Append() {
filename[7] = 'B';
Mmc_Fat_Assign(&filename, 0);
Mmc_Fat_Set_File_Date(2005,6,21,10,35,0);
Mmc_Fat_Append();
PORTD = 0x08; // Prepare file for append
Mmc_Fat_Write(" for mikroElektronika 2005\n", 27); // Write data to assigned file
}//~

void main() {
//--- prepare PORTB for signalling
PORTB = 0;
TRISB = 0x10;
INTCON2.F7=0;
TRISD = 0x00;
TRISC = 0xD3;
//--- init the FAT library
Spi_Init_Advanced(MASTER_OSC_DIV16, DATA_SAMPLE_MIDDLE, CLK_IDLE_LOW, LOW_2_HIGH);





if (Mmc_Fat_Init(&PORTC,2))
{
//--- Test start
PORTD = 0xF0;
//--- Test routines. Uncomment them one-by-one to test certain features


//M_Create_New_File();
M_Open_File_Append();
}

else {
I_Write_Str(FAT_ERROR);
}
//--- Test termination
PORTD = 0x0F;


}//~!


if I use the function: M_Create_New_File (); all right.
if I use the function: M_Open_File_Append (); does not work.
Why?
My compiler is mikroC v.6.2
The device is P18F458 HSPLL = 40MHz with quartz 10MHz.
Thanks, Regards.
