35 .Nd return the checksum of an ELF object
41 .Fn elf32_checksum "Elf *elf"
43 .Fn elf64_checksum "Elf *elf"
46 .Fn gelf_checksum "Elf *elf"
48 These functions return a simple checksum of the ELF object described
51 The checksum is computed in way that allows its value to remain
52 unchanged in presence of modifications to the ELF object by utilities
58 returns a checksum for an ELF descriptor
65 returns a checksum for an ELF descriptor
72 provides a class-independent way retrieving the checksum
76 These functions return the checksum of the ELF object, or zero in case
77 an error was encountered.
79 These functions may fail with the following errors:
80 .Bl -tag -width "[ELF_E_RESOURCE]"
81 .It Bq Er ELF_E_ARGUMENT
85 .It Bq Er ELF_E_ARGUMENT
88 was not a descriptor for an ELF file.
89 .It Bq Er ELF_E_ARGUMENT
92 was not opened for reading or updating.
100 did not match the class of the called function.
101 .It Bq Er ELF_E_HEADER
102 The ELF object specified by argument
104 had a malformed executable header.
105 .It Bq Er ELF_E_RESOURCE
106 An out of memory condition was detected during processing.
107 .It Bq Er ELF_E_SECTION
108 The ELF object specified by argument
110 contained a section with a malformed section header.
111 .It Bq Er ELF_E_VERSION
112 The ELF object was of an unsupported version.
