I'm nit-picking, but it isn't always the case that sizeof is compile-time.

C99 allows sizeof to be runtime for VLA's.

To the OP: it would be a good idea to check the return values from all the socket and i/o functions you're using... you're flying blind, not knowing what is happening.

elf64_fsize

elf_fsize(3E)															     elf_fsize(3E)

NAME

       elf32_fsize,  elf64_fsize - return the size of an object file type for elf32 files, return the size of an object file type for elf64 files,
       respectively.

SYNOPSIS

       [flag... ] file...  [library] ...

DESCRIPTION

       gives the size in bytes of the 32-bit file representation of count data objects with the given type.  The library uses version ver to  cal-
       culate the size (see elf(3E) and elf_version(3E)).

       Constant values are available for the sizes of fundamental types.

						  Elf_Type	File Size	  Memory Size
						  ------------------------------------------------------
						  ELF_T_ADDR	ELF32_FSZ_ADDR	  sizeof(Elf32_Addr)
						  ELF_T_BYTE	1		  sizeof(unsigned char)
						  ELF_T_HALF	ELF32_FSZ_HALF	  sizeof(Elf32_Half)
						  ELT_T_OFF	ELF32_FSZ_OFF	  sizeof(Elf32_Off)
						  ELF_T_SWORD	ELF32_FSZ_SWORD   sizeof(Elf32_Sword)
						  ELF_T_WORD	ELF32_FSZ_WORD	  sizeof(Elf32_Word)

       returns zero if the value of type or ver is unknown.  See elf_xlate(3E) for a list of the type values.

       gives  the size in bytes of the 64-bit file representation of count data objects with the given type.  The library uses version ver to cal-
       culate the size (see elf(3E) and elf_version(3E)).

       Constant values are available for the sizes of fundamental types.

						  Elf_Type	File Size	  Memory Size
						  ------------------------------------------------------
						  ELF_T_ADDR	ELF64_FSZ_ADDR	  sizeof(Elf64_Addr)
						  ELF_T_BYTE	1		  sizeof(unsigned char)
						  ELF_T_HALF	ELF64_FSZ_HALF	  sizeof(Elf64_Half)
						  ELT_T_OFF	ELF64_FSZ_OFF	  sizeof(Elf64_Off)
						  ELF_T_SWORD	ELF64_FSZ_SWORD   sizeof(Elf64_Sword)
						  ELF_T_WORD	ELF64_FSZ_WORD	  sizeof(Elf64_Word)

       returns zero if the value of type or ver is unknown.  See elf_xlate(3E) for a list of the type values.
