CONFORMING TO The four functions getc_unlocked(), getchar_unlocked(), putc_unlocked(), putchar_unlocked() are in POSIX.1-2001 and POSIX.1-2008. The nonstandard *_unlocked() variants occur on a few UNIX systems, and are available in recent glibc.They should probably not be used. SEE ALSO flockfile(3), stdio(3) COLOPHON This page is part of release 4.13 of the Linux man-pages project. fread() reads up to length bytes from the file pointer referenced by stream.Reading stops as soon as one of the following conditions is met: length bytes have been read ; EOF (end of file) is reached a packet becomes available or the socket timeout occurs (for network streams) ; if the stream is read buffered and it does not represent a plain file, at most one read of up to a number of bytes The program below demonstrates the use of fread() by parsing /bin/sh ELF executable in binary mode and printing its magic and class: This page is part of release 5.13 of the Linux man-pages project. A description of the project, 2021-03-22 GNU Linux Programmer's Manual. The fread () function reads into the array pointed to by ptr up to nitems elements whose size is specified by size in bytes, from the stream pointed to by stream. For each object, size calls are made to the fgetc (3C) function and the results stored, in the order read, in an array of unsigned char exactly overlaying the object. integer data types specified by POSIX.1. On Linux, read() (and similar system calls) will transfer at most 0x7ffff000 (2,147,479,552) bytes, returning the number of bytes actually transferred. (This is true on both 32-bit and 64-bit systems.) On NFS filesystems, reading small amounts of data will update the fread - Man Page. binary input. Prolog.

NAME. fread, fwrite - binary stream input/output SYNOPSIS The function fread() reads nmemb items of data, each size bytes long, from the stream pointed to by stream, storing them at the location given by ptr. The following example shows the usage of fread () function. Let us compile and run the above program that will create a file file.txt and write a content this is tutorialspoint. After that, we use fseek () function to reset writing pointer to the beginning of the file and prepare the file content which is as follows −. The zip_fread function reads at most nbytes bytes from file into buf. RETURN VALUES If successful, the number of bytes actually read is returned. Otherwise, -1 is returned.
