NAME
elf_strptr - make a string pointer
SYNOPSIS
[flag... ] file... [library] ...
DESCRIPTION
This function converts a string section offset to a string pointer. elf identifies the file in which the string section resides, and sec-
tion gives the section table index for the strings. 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 the section data cannot be obtained, offset is invalid, or an error occurs.
EXAMPLES
A prototype for retrieving section names appears below. The file header specifies the section name string table in the member. The fol-
lowing code loops through the sections, printing their names.
if ((ehdr = elf32_getehdr(elf)) == 0)
{
/* handle the error */
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'
", name? name: "(null)");
}
Note
A program may call to retrieve an entire string table section. For some applications, that would be both more efficient and more conve-
nient than using
