elf_strptr(3elf)

elf_strptr(3ELF)             ELF Library Functions            elf_strptr(3ELF)



NAME
       elf_strptr - make a string pointer

SYNOPSIS
       cc [ flag ... ] file ... -lelf [ library ... ]
       #include <libelf.h>

       char *elf_strptr(Elf *elf, size_t section, size_t offset);

DESCRIPTION
       The  elf_strptr() function converts a string section offset to a string
       pointer. elf identifies the file in which the string  section  resides,
       and  section  identifies  the  section  table  index  for  the strings.
       elf_strptr() normally returns a pointer to a string, but it  returns  a
       null  pointer  when elf is null, section is invalid or is not a section
       of type SHT_STRTAB, the section data  cannot  be  obtained,  offset  is
       invalid, or an error occurs.

EXAMPLES
       Example 1 A sample program of calling elf_strptr() function.




       A prototype for retrieving section names appears below. The file header
       specifies the section name string table in the e_shstrndx  member.  The
       following code loops through the sections, printing their names.


         /* handle the error */
         if ((ehdr = elf32_getehdr(elf)) == 0) {
              return;
         }
         ndx = ehdr->e_shstrndx;
         scn = 0;
         while ((scn = elf_nextscn(elf, scn)) != 0) {
              char *name = 0;
              if ((shdr = elf32_getshdr(scn)) != 0)
                         name = elf_strptr(elf, ndx, (size_t)shdr->sh_name);
              printf("'%s'\n", name? name: "(null)");
         }

NOTES
       When  applied  to  a compressed string table section, elf_strptr() will
       return pointers to uncompressed strings, without causing the string ta‐
       ble section to be uncompressed.


       A  program  may  call  elf_getdata() to retrieve an entire string table
       section. For some applications, that would be both more  efficient  and
       more convenient than using elf_strptr().
