Detailed Description

Function Documentation

int32_t fsys_init_dir	(	user_type *	user_list,
		mmc_function_type *	mmc_func
	)

Parameters

user_list	- directory list
mmc_func	- multi media card support function

Returns

• TRUE success
• FALSE error

Library:

net.lib

Prototype:

net.h

int32_t fsys_init_file	(	direntry_type *	fp,
		uint32_t	offset,
		int32_t	size
	)

When file position or size has been changed, use this function to correct internal file parameters. Otherwise for no changes set offset or size to zero.

Parameters

fp	- file pointer
offset	- new offset
size	- new size

Returns

• TRUE success
• FALSE error

Library:

net.lib

Prototype:

net.h

Examples:

Telnet.c.

int32_t fsys_get_file_size

(

direntry_type *

fp

)

Note

Reading size is only possible for ASCII type; for binary file type size the maximum value specified in user_list is taken.

Parameters

*fp	- pointer to directory entry

Returns

file size

Library:

net.lib

Prototype:

net.h

Examples:

Telnet.c.

direntry_type * fsys_send_all	(	direntry_type *	fp,
		int32_t	size,
		int32_t	send_all
	)

This multi-purpose file transmission function allows to send or receive data (ASCII, binary or Intel-Hex) from or to FLASH/RAM space via connected TCP socket.

Parameters

fp	- file to send
size	- some bytes left to send from previous packet
send_all	- if TRUE all data will be sent immediately (blocking mode)

Returns

• pointer to file = sending not finished
• NULL = all bytes transmitted

Library:

net.lib

Prototype:

net.h

void fsys_init_flash

(

void

)

Tag all FLASH-sectors as not empty for correct sector erase. Must be called before data is written into FLASH memory via fsys_send_all().

Parameters

Returns

nothing
