44 These convenience functions are used to retrieve and update class-dependent
48 structures in an ELF object.
54 descriptor associated with a section of type
58 is the index of the entry being retrieved or updated.
61 structure is described in
66 retrieves the class-dependent entry at index
70 and copies it to the destination pointed to by argument
72 after translation to class-independent form.
76 converts the class-independent entry pointed to
79 to class-dependent form, and writes it to the entry at index
81 in the data buffer described by argument
85 signals an error if any of the values in the class-independent
86 representation exceeds the representable limits of the target
91 returns the value of argument
93 if successful, or NULL in case of an error.
96 returns a non-zero value if successful, or zero in case of an error.
98 These functions may fail with the following errors:

116 .It Bq Er ELF_E_RANGE
117 A value was not representable in the target type.
