NAMEelf_strptr — make a string pointer SYNOPSISInvocation: cc [flag]... file... -lelf [library]... #include <libelf.h> char *elf_strptr( Elf *elf, size_t section, size_t offset ); DESCRIPTIONThis function converts a string section offset to a string pointer. elf identifies the file in which the string section resides, and section gives the section table index for the strings. RETURN VALUEelf_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. EXAMPLESA 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. 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'\n", name? name: "(null)"); } |
