Is this homework? If so please post it in the homework section.

Bad English is one thing, but it is also a bit difficult to understand what you wrote. Are you talking about converting a text file with external decimal representations into a binary file with internal decimal representations? What do you mean with "the file's specifiers " ?

NAME
xdr_simple, xdr_bool, xdr_char, xdr_double, xdr_enum, xdr_float, xdr_free, xdr_hyper, xdr_int, xdr_long, xdr_longlong_t, xdr_quadruple, xdr_short, xdr_u_char, xdr_u_hyper, xdr_u_int, xdr_u_long, xdr_u_longlong_t, xdr_u_short, xdr_void - library routines for external data representation SYNOPSIS
DESCRIPTION
XDR library routines allow C programmers to describe simple data structures in a machine-independent fashion. Protocols such as remote procedure calls (RPC) use these routines to describe the format of the data. These routines require the creation of XDR streams (see xdr_create(3N)). Routines See rpc(3N) for the definition of the data structure. Note that any buffers passed to the XDR routines must be properly aligned. It is suggested that malloc(3C) be used to allocate these buffers or that the programmer insure that the buffer address is divisible evenly by four. translates between booleans (C integers) and their external representations. When encoding data, this filter produces values of either or This routine returns if it suc- ceeds, otherwise. translates between C characters and their external representations. This routine returns if it succeeds, otherwise. Note: encoded characters are not packed, and occupy 4 bytes each. For arrays of characters, it is worthwhile to consider or (see xdr_complex(3N)). translates between C precision numbers and their external representations. This routine returns if it succeeds, otherwise. translates between C (actually integers) and their external representations. This routine returns if it succeeds, otherwise. translates between C and their external representations. This routine returns if it succeeds, otherwise. Generic freeing routine. The first argument is the XDR routine for the object being freed. The second argument is a pointer to the object itself. Note: the pointer passed to this routine is not freed, but what it points to is freed (recursively, depending on the XDR routine). translates between ANSI C integers and their external representations. This routine returns if it succeeds, otherwise. translates between C integers and their external representations. This routine returns if it succeeds, otherwise. translates between C integers and their external representations. This routine returns if it succeeds, otherwise. translates between ANSI C integers and their external representations. This routine returns if it succeeds, otherwise. This routine is identical to translates between IEEE quadruple precision floating point numbers and their external representations. This routine returns if it succeeds, otherwise. translates between C integers and their external representations. This routine returns if it succeeds, otherwise. translates between C characters and their external representations. This routine returns if it succeeds, otherwise. translates between unsigned ANSI C integers and their external representations. This routine returns if it succeeds, otherwise. A filter primitive that translates between a C integer and its external representation. This routine returns if it succeeds, otherwise. translates between C integers and their external representations. This routine returns if it succeeds, otherwise. translates between unsigned ANSI C integers and their external representations. This routine returns if it succeeds, otherwise. This routine is identical to translates between C integers and their external representations. This routine returns if it succeeds, otherwise. This routine always returns It may be passed to RPC routines that require a function parameter, where nothing is to be done. MULTITHREAD USAGE
Thread Safe: Yes Cancel Safe: Yes Fork Safe: No Async-cancel Safe: No Async-signal Safe: No These functions can be called safely in a multithreaded environment. They may be cancellation points in that they call functions that are cancel points. In a multithreaded environment, these functions are not safe to be called by a child process after and before These functions should not be called by a multithreaded application that support asynchronous cancellation or asynchronous signals.
