403 | FUNCTION | |
404 | bfd_get_size | |
405 | ||
406 | DESCRIPTION | |
407 | These macros as used for reading and writing raw data in | |
408 | sections; each access (except for bytes) is vectored through | |
409 | the target format of the BFD and mangled accordingly. The | |
410 | mangling performs any necessary endian translations and | |
411 | removes alignment restrictions. Note that types accepted and | |
412 | returned by these macros are identical so they can be swapped | |
413 | around in macros---for example, @file{libaout.h} defines <<GET_WORD>> | |
414 | to either <<bfd_get_32>> or <<bfd_get_64>>. | |
415 | ||
416 | In the put routines, @var{val} must be a <<bfd_vma>>. If we are on a | |
417 | system without prototypes, the caller is responsible for making | |
418 | sure that is true, with a cast if necessary. We don't cast | |
419 | them in the macro definitions because that would prevent <<lint>> | |
420 | or <<gcc -Wall>> from detecting sins such as passing a pointer. | |
421 | To detect calling these with less than a <<bfd_vma>>, use | |
422 | <<gcc -Wconversion>> on a host with 64 bit <<bfd_vma>>'s. | |

485 | These macros have the same function as their <<bfd_get_x>> | |
dc810e39 | 486 | brethren, except that they are used for removing information |
252b5132 RH |
487 | for the header records of object files. Believe it or not, |
488 | some object files keep their header records in big endian | |
489 | order and their data in little endian order. | |
