Detailed Description

Label File access functions

NOTE: before accessing the SD Card, the upper level function should synchronize with the SD Card semaphore! MUTEX_SDCARD_TAKE; // to take the semaphore MUTEX_SDCARD_GIVE; // to release the semaphore

Function Documentation

s32 generateNglFileMD5	(	char *	filepath,
		u8	md5_checksum[16]
	)

creates the MD5 checksum over the .NGL file

Returns:

< 0 on errors

Here is the call graph for this function:

s32 MBNG_FILE_L_Debug

(

void

)

sends label data to debug terminal

Returns:

< 0 on errors

const char* MBNG_FILE_L_GetLabel	(	char *	label,
		u16	value
	)

Returns:

the content of a label for a given value SDCARD mutex handled automatically if SD Card really has to be accessed

Here is the call graph for this function:

s32 MBNG_FILE_L_Init

(

u32

mode

)

Initialisation

Here is the call graph for this function:

s32 MBNG_FILE_L_Load

(

char *

filename

)

Loads patch file Called from MBNG_FILE_CheckSDCard() when the SD card has been connected

Returns:

< 0 on errors

Here is the call graph for this function:

s32 MBNG_FILE_L_Read

(

char *

filename

)

Here is the call graph for this function:

s32 MBNG_FILE_L_Unload

(

void

)

Unloads label file Called from MBNG_FILE_CheckSDCard() when the SD card has been disconnected

Returns:

< 0 on errors

s32 MBNG_FILE_L_Valid

(

void

)

Returns:

1 if current label file valid

0 if current label file not valid

s32 MBNG_FILE_L_Write

(

char *

filename

)

writes data into label file

Returns:

< 0 on errors (error codes are documented in seq_file.h)

Here is the call graph for this function:

s32 parseBinFile

(

char *

filepath

)

parse the .BIN file for labels < 0 on errors

Here is the call graph for this function:

s32 readBinFileMD5	(	char *	filepath,
		u8	md5_checksum[16]
	)

read the .BIN file and checks if it is valid md5_checksum_binfile[16] contains the expected MD5 checksum of the .NGL file if valid

Returns:

< 0 on errors

Here is the call graph for this function:

Variable Documentation

char filepath[MAX_PATH]

reads the label file content (again)

Returns:
