Re: [sqlite] Help with sqlite3OsRead - porting to a new OS

[David Garfield]

Also, if this is debugger output (as it appears), it could be that an
optimizer is confusing the parameters.  I see that all the time on GCC
i386 when I set a breakpoint at the start of a function.

Sounds like it could be a difference in calling convention...  Check
compile options and function declaration modifiers.

[sqlite] Help with sqlite3OsRead - porting to a new OS

[Stuart Thomson]

Hi,

I'm in the middle of porting sqlite3 to a new Operating System and have come 
across a problem with the sqlite3OsRead function in the 
sqlite3PagerReadFileheader function body.

Before the sqlite3OsRead function is called, the parameters are correctly 
populated

for example:
pPager->fd= \u565c,  0x6208565c
pDest= \ufea8,   0x2000fea8
N  = d,  0x0064
Offset= 0

But when the function sqlite3OsRead is actually implemented the parameters are 
in the incorrect order. More specifically:

Sqlite3_file *id= d,  0x0064
Void *pBuf = \u565c,  0x6208565c
Int amt  = \ufea8,   0x2000fea8
I64 offset   = \0,  0x2000fea8

I have built a Database using sqlite3 3.7.5 and the code is built to 3.7.5.

Any ideas are welcome,

Cheers
Stuart
