Ok, I do the beginning. Please Post only technical articles here.
@Mod please make this sticky
File Handling fopen Code:
typedef int (*g_fopen)(const char * cFileName, unsigned int iFileFlags, unsigned int iFileMode, unsigned int *ErrorNumber);
g_fopen fopen = (g_fopen)(0xA1230050); // S65 FW47
// Pattern: FE402DE90270A0E10160A0E10350A0E10040A0E1????????0030E0E304308DE500508DE52CC090E5
fclose Code:
typedef void (*g_fclose)(int FileHandler, unsigned int *ErrorNumber);
g_fclose fclose = (g_fclose)(0xA122FFA4); // S65 FW47
// Pattern: 38402DE90150A0E10040A0E1????????00C090E5
fflush Code:
typedef void (*g_fflush)(int FileHandler, unsigned int *ErrorNumber);
g_fflush fflush = (g_fflush)(0xA122FFD4); // S65 FW47
// Pattern: 38402DE90150A0E10040A0E1????????08C090E5
lseek Code:
typedef unsigned int (*g_lseek)(int FileHandler, unsigned int offset, unsigned int origin, unsigned int *ErrorNumber);
// g_lseek lseek = (g_lseek)(0xA1230004); // S65 FW47
// Pattern: FF412DE928509DE50280A0E10170A0E10360A0E10040A0E1
fread Code:
typedef void (*g_fread)(int FileHandler, char *cBuffer, int iByteCount, unsigned int *ErrorNumber);
g_fread fread = (g_fread)(0xA1230090); // S65 FW47
// Pattern: FE402DE90270A0E10160A0E10350A0E10040A0E1????????0030E0E304308DE500508DE530C090E5
fwrite Code:
typedef void (*g_fwrite)(int FileHandler, const char * cBuffer, int iByteCount, unsigned int *ErrorNumber);
g_fwrite fwrite = (g_fwrite)(0xA1230178); // S65 FW47

SetFileSize Code:
typedef void (*g_SetFileSize)(int FileHandler, unsigned int iNewFileSize, unsigned int *ErrorNumber);
g_SetFileSize SetFileSize = (g_SetFileSize)(0xA12300D0); // S65 FW47
// Pattern: 7C402DE90160A0E10250A0E10040A0E1????????0030E0E300308DE544C090E5
Constants Seek Code:

#define S_CUR 1
#define S_END 2
Permissions Code:

Sample - File Read Code:
int iFileHandler
unsigned int iError;
unsigned int iFileSize;
unsigned int iFilePos;
char *cFileOutput = (char*)0xA8100000;
// file read example:
iFileHandler = fopen("0:\\test.bin\0", A_ReadOnly, P_READ, &iError);
if (iFileHandler != -1) {
// get the file size:
iFileSize = lseek(iFileHandler, 0, S_END, &iError);
if (iFileSize > 0) {
// seek the beginning of the file:
iFilePos = lseek(iFileHandler, 0, S_SET, &iError);
// read complete file:
fread(iFileHandler, cFileOutput, iFileSize, &iError);
}
// close the file
fclose(iFileHandler, &iError);
} else {
// File not found
} Sample - File Write Code:
int iFileHandler
unsigned int iError;
unsigned int iFileSize;
unsigned int iFilePos;
char *cFileOutput = (char*)0xA8100000;
// create file if it does not exist:
iFileHandler = fopen("0:\\outfile.txt\0", A_Create, P_WRITE, &iError);
fclose(iFileHandler, &iError);
iFileHandler = fopen("0:\\outfile.txt\0", A_WriteOnly, P_WRITE, &iError);
if (iFileHandler != -1) {
// search the end of the file
iFileSize = lseek(iFileHandler, 0, S_END, &iError);
// add an line
fwrite(iFileHandler, "new line\x0D\x0A", 10, &iError);
// close the file
fclose(iFileHandler, &iError);
