37 .Fn elf_getphdrnum "Elf *elf" "size_t *phnum"
41 retrieves the number of ELF program headers associated with descriptor
43 and stores it into the location pointed to by argument
46 This routine allows applications to uniformly process both normal ELF
47 objects and ELF objects that use extended numbering.
52 returns a zero value if successful, or -1 in case of an error.
56 can fail with the following errors:
57 .Bl -tag -width "[ELF_E_RESOURCE]"

59 A NULL value was passed in for argument
61 .It Bq Er ELF_E_ARGUMENT
64 was not for an ELF file.
65 .It Bq Er ELF_E_ARGUMENT
68 lacks an ELF Executable Header.
69 .It Bq Er ELF_E_HEADER
