EL_CalcEnoughBufferSizeforLink*

Syntax

#include <twl/el.h>

s32 EL_CalcEnoughBufferSizeforLink( ELReadImage readfunc, u32 len, const void* buf, ELLinkMode link_mode );
s32 EL_CalcEnoughBufferSizeforLinkFile( const char* FilePath, const void* buf, ELLinkMode link_mode);
s32 EL_CalcEnoughBufferSizeforLinkImage( void* obj_image, u32 obj_len, const void* buf, ELLinkMode link_mode );

Arguments

readfunc Developer-specific Read function.
FilePath Path name of the dynamic module to register.
obj_image Memory address of the dynamic module to register.
len / obj_len Size of the dynamic module to register.
buf Buffer where the dynamic module will be registered.
Nothing is actually written here.
link_mode Mode when the dynamic link is tested.
As of now, the only mode that can be specified is EL_LINKMODE_ONESHOT.

Return Values

If the process succeeds, the function returns the required buffer size.
If it fails, it returns a value of -1.

Description

Determines what size buffer is enough to register the dynamic module to the EL library.
If the dynamic module makes external references, this function may return a somewhat larger size.

The EL_CalcEnoughBufferSizeforLink function uses the user-specified read function to read the dynamic module.
The EL_CalcEnoughBufferSizeforLinkFile function reads the dynamic module being registered from ROM.
The EL_CalcEnoughBufferSizeforLinkImage function uses the dynamic module that has been loaded into memory.
