44 These convenience functions are used to retrieve and update class-dependent
50 table of an ELF object.
56 descriptor associated with a section of type
60 is the index of the entry being retrieved or updated.
63 structure is described in
68 retrieves the class-dependent entry at index
72 and copies it to the destination pointed to by argument
74 after translation to class-independent form.
78 converts the class-independent entry pointed to
81 to class-dependent form, and writes it to the entry at index
83 in the data buffer described by argument
87 signals an error if any of the values in the class-independent
88 representation exceeds the representable limits of the target
93 returns the value of argument
95 if successful, or NULL in case of an error.
98 returns a non-zero value if successful, or zero in case of an error.
100 These functions may fail with the following errors:
101 .Bl -tag -width "[ELF_E_RESOURCE]"
102 .It Bq Er ELF_E_ARGUMENT
108 .It Bq Er ELF_E_ARGUMENT
111 was less than zero or larger than the number of entries in the data
113 .It Bq Er ELF_E_ARGUMENT
116 was not associated with a section of type
118 .It Bq Er ELF_E_RANGE
119 A value was not representable in the target type.
