Read from stream

[Classification]

Standard library

[Syntax]

#include <stdio.h>

size_t fread(void *ptr, size_t size, size_t nmemb, FILE *stream);

[Return value]

The number of elements that were input (nmemb) is returned.

Error return does not occur.

[Description]

This function inputs nmemb elements of size from the input stream pointed to by stream and stores them in ptr. Only the standard input/output stdin can be specified for stream.

[Example]

#include    <stdio.h>

void func(void) {

        struct {

                int     c;

                double  d;

        } buf[10];

        fread(buf, sizeof(buf[0]), sizeof(buf) / sizeof(buf [0]), stdin);

}
