Detailed Description

A SEC is modeled after the sections found inside elf images. Can be accessed at instrumentation time and analysis time.

SECs can be mapped or unmapped, a mapped SEC occupies address space inside the IMG. Unmapped SECs often contain debug and relocation information.
APIs from this group are available in any thread, including any internal thread spawned by the tool.

Iteration idioms:

  // Forward pass over all sections in an image
  for( SEC sec= IMG_SecHead(img); SEC_Valid(sec); sec = SEC_Next(sec) )

  // Reverse pass over all sections in animage
  for( SEC sec= IMG_SecTail(img); SEC_Valid(sec); sec = SEC_Prev(sec) )

Function Documentation

ADDRINT LEVEL_PINCLIENT::SEC_Address ( SEC sec )

Returns:: Address in memory of sec

If image is loaded by system loader, the real virtual address of section will be returned. If the image is mapped by IMG_Open() the address will be inside the mapped image. On Unix, if the section is not loadable, 0 will be returned in the both cases.

const VOID* LEVEL_PINCLIENT::SEC_Data ( SEC sec )

Returns:: Return a pointer to the raw data for the section

On Linux, Pin maps the whole image file for processing. The pointer returned by SEC_Data() points inside the mapped file. Note, SEC_Data() pointer is always between IMG_StartAddress() and IMG_StartAddress() + IMG_SizeMapped(). If you are analyzing image in image-load callback, please remember that the image will be unmapped after the callback returns and the pointer provided by SEC_Data() becomes invalid. If you are working with IMG_Open() the pointer is valid until IMG_Close().

If section does not have raw data the function returns 0.
