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' ", name? name: "(null)"); } ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Interface Stability |Stable | +-----------------------------+-----------------------------+ |MT-Level |MT-Safe | +-----------------------------+-----------------------------+ SEE ALSO
elf(3ELF), elf32_getshdr(3ELF), elf32_xlatetof(3ELF), elf_getdata(3ELF), libelf(3LIB), attributes(5) NOTES
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(). SunOS 5.10 11 Jul 2001 elf_strptr(3ELF)
