ddpi_elf_load_cu operation

The ddpi_elf_load_cu operation loads and relocates the ELF object file.

This operation verifies that the ELF object (inside the Ddpi_Elf object) has an MD5 signature that matches the CU that has been loaded into memory. If a match is found, the operation adjusts the relocatable physical addresses of the ELF object to correspond to the physical addresses of the CU that has been loaded into memory.

Prototype

int  ddpi_elf_load_cu(              
     Ddpi_Info           info,    
     Ddpi_Elf            pi_elf,  
     Ddpi_Error*         error);

Parameters

info: Input. This input parameter accepts the Ddpi_Info processing object.
pi_elf: Input. This accepts the Ddpi_Elf object containing the file-specific ELF object.
error: See The libddpi error parameter.

Return values

DW_DLV_OK

This value is returned upon verification that the ELF object (inside the Ddpi_Elf object) has an MD5 signature that matches the CU that has been loaded in memory.

DW_DLV_ERROR

This value is returned if:

pi_elf is NULL
pi_elf does not have a valid ELF descriptor
The ELF descriptor contains invalid relocation types
There is insufficient memory

DW_DLV_NO_ENTRY

This value is returned if the MD5 signature does not match the CU that is loaded in memory.
