1 gru 2022 · fread returns the number of full items the function read, which may be less than count if an error occurs, or if it encounters the end of the file before reaching count. Use the feof or ferror function to distinguish a read error from an end-of-file condition.
21 gru 2011 · The fread() function shall read 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 shall be made to the fgetc() function and the results stored , in the order read, in an array of unsigned char exactly overlaying the object.
1 gru 2022 · fread_s returns the number of (whole) items that were read into the buffer, which may be less than count if a read error or the end of the file is encountered before count is reached. Use the feof or ferror function to distinguish an error from an end-of-file condition.
17 wrz 2024 · The C fread () is a standard library function used to read the given amount of data from a file stream. Defined inside <stdio.h>, the fread () function reads the given number of elements of specific size from the file stream and stores it in the buffer memory.
9 maj 2023 · fread. Reads up to count objects into the array buffer from the given input stream stream as if by calling fgetc size times for each object, and storing the results, in the order obtained, into the successive positions of buffer, which is reinterpreted as an array of unsignedchar.
int main (void) {FILE * file = fopen ("cs50.txt", "r"); if (file!= NULL) {char c; while (fread (& c, sizeof (char), 1, file)) {printf ("%c", c);} fclose (file);}} The program below demonstrates the use of fread () by parsing /bin/sh ELF executable in binary mode and printing its magic and class:
fread. size_t fread ( void * ptr, size_t size, size_t count, FILE * stream ); Read block of data from stream. Reads an array of count elements, each one with a size of size bytes, from the stream and stores them in the block of memory specified by ptr. The position indicator of the stream is advanced by the total amount of bytes read.
