elf_memory
(char

elf_memory
() is used to process an ELF file or
ar(1) archive whose image is present
in memory.
Argument image points to the start of the memory image of the file or archive. Argument size contains the size in bytes of the memory image.
The ELF descriptor is created for reading (i.e., analogous to the
use of elf_begin(3) with a
command argument value of ELF_C_READ
).
elf_memory
() returns a pointer to a new ELF
descriptor if successful, or NULL if an error occurred.
The return value may be queried for the file type using elf_kind(3).
int fd; void *p; struct stat sb; Elf *e; ... if ((fd = open("./elf-file", O_RDONLY)) < 0 || fstat(fd, &sb) < 0 || (p = mmap(NULL, sb.st_size, PROT_READ, MAP_PRIVATE, fd, (off_t) 0)) == MAP_FAILED) { ... handle system error ... } if ((e = elf_memory(p, sb.st_size)) == NULL) { ... handle elf(3) error ... } ... use ELF descriptor "e" here ...

errors:
