dl_iterate_phdr(int
(*callback)(struct dl_phdr_info *, size_t, void*),
void *data);
dl_iterate_phdr() function iterates over all shared
objects loaded into a process's address space, calling
callback for each shared object, passing it information
about the object's program headers and the data
argument. The information about the program headers is passed in a structure
that is defined as:
struct dl_phdr_info {
Elf_Addr dlpi_addr;
const char *dlpi_name;
const Elf_Phdr *dlpi_phdr;
Elf_Half dlpi_phnum;
unsigned long long int dlpi_adds;
unsigned long long int dlpi_subs;
size_t dlpi_tls_modid;
void *dlpi_tls_data;
};
The members of struct dl_phdr_info have
the following meaning:
To make it possible for programs to check whether any new members have been added, the size of the structure is passed as an argument to callback.
dl_iterate_phdr function first appeared in
NetBSD 6.0.
