Problems with Data Types, Medium Severity (1)

libjio.h
[+] struct jfs (1)

	Change	Effect
1	Field ltlock has been added at the middle position of this structural type.	1) Size of the inclusive type has been changed. 2) Layout of structure fields has been changed and therefore fields at higher positions of the structure definition may be incorrectly accessed by applications.

[+] affected symbols (28)

1st parameter 'stream' (pointer) has base type 'struct jfs'.

jclose ( struct jfs* fs )

1st parameter 'fs' (pointer) has base type 'struct jfs'.

jfclose ( struct jfs* stream )

1st parameter 'stream' (pointer) has base type 'struct jfs'.

Return value (pointer) has base type 'struct jfs'.

jfread ( void* ptr, size_t size, size_t nmemb, struct jfs* stream )

4th parameter 'stream' (pointer) has base type 'struct jfs'.
