GELF_GETCAP(3)						   BSD Library Functions Manual 					    GELF_GETCAP(3)

NAME

     gelf_getcap, gelf_update_cap -- read and update ELF capability information

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <gelf.h>

     GElf_Cap *
     gelf_getcap(Elf_Data *data, int ndx, GElf_Cap *cap);

     int
     gelf_update_cap(Elf_Data *data, int ndx, GElf_Cap *cap);

DESCRIPTION

     These convenience functions are used to retrieve and update class-dependent Elf32_Cap or Elf64_Cap information.

     Argument data is an Elf_Data descriptor associated with a section of type SHT_SUNW_cap.  Argument ndx is the index of the entry being
     retrieved or updated.  The class-independent GElf_Cap structure is described in gelf(3).

     Function gelf_getcap() retrieves the class-dependent entry at index ndx in data buffer data and copies it to the destination pointed to by
     argument cap after translation to class-independent form.

     Function gelf_update_cap() converts the class-independent entry pointed to by argument cap to class-dependent form, and writes it to the
     entry at index ndx in the data buffer described by argument data.	Function gelf_update_cap() signals an error if any of the values in the
     class-independent representation exceeds the representable limits of the target type.

RETURN VALUES

     Function gelf_getcap() returns the value of argument cap if successful, or NULL in case of an error.  Function gelf_update_cap() returns a
     non-zero value if successful, or zero in case of an error.

ERRORS

     These functions may fail with the following errors:

     [ELF_E_ARGUMENT]  Arguments data or cap were NULL.

     [ELF_E_ARGUMENT]  Argument ndx was less than zero or larger than the number of entries in the data descriptor.

     [ELF_E_ARGUMENT]  Data descriptor data was not associated with a section of type SHT_SUNW_cap.

     [ELF_E_RANGE]     A value was not representable in the target type.

GELF_GETRELA(3) 					   BSD Library Functions Manual 					   GELF_GETRELA(3)

NAME

     gelf_getrela, gelf_update_rela -- read and update ELF relocation entries with addends

LIBRARY

     ELF Access Library (libelf, -lelf)

SYNOPSIS

     #include <gelf.h>

     GElf_Rela *
     gelf_getrela(Elf_Data *data, int ndx, GElf_Rela *rela);

     int
     gelf_update_rela(Elf_Data *data, int ndx, GElf_Rela *rela);

DESCRIPTION

     These convenience functions are used to retrieve and update class-dependent Elf32_Rela or Elf64_Rela structures in an ELF object.

     Argument data is an Elf_Data descriptor associated with a section of type SHT_RELA.  Argument ndx is the index of the entry being retrieved
     or updated.  The class-independent GElf_Rela structure is described in gelf(3).

     Function gelf_getrela() retrieves the class-dependent entry at index ndx in data buffer data and copies it to the destination pointed to by
     argument rela after translation to class-independent form.

     Function gelf_update_rela() converts the class-independent entry pointed to by argument rela to class-dependent form, and writes it to the
     entry at index ndx in the data buffer described by argument data.	Function gelf_update_rela() signals an error if any of the values in the
     class-independent representation exceeds the representable limits of the target type.

RETURN VALUES

     Function gelf_getrela() returns the value of argument rela if successful, or NULL in case of an error.  Function gelf_update_rela() returns a
     non-zero value if successful, or zero in case of an error.

ERRORS

     These functions may fail with the following errors:

     [ELF_E_ARGUMENT]  Arguments data or rela were NULL.

     [ELF_E_ARGUMENT]  Argument ndx was less than zero or larger than the number of entries in the data descriptor.

     [ELF_E_ARGUMENT]  Data descriptor data was not associated with a section of type SHT_RELA.

     [ELF_E_RANGE]     A value was not representable in the target type.
