fgetc, getc

Defined in header <stdio.h> 
int fgetc( FILE *stream );
-		 (1) 
int getc( FILE *stream );
-		 (2)
-1) Reads the next character from the given input stream.
-2) Same as fgetc, except that if getc is implemented as a macro, it may evaluate stream more than once, so the corresponding argument should never be an expression with side effects.

Parameters

- -
stream - to read the character from

Return value

On success, returns the obtained character as an unsigned char converted to an int. On failure, returns EOF.

-

If the failure has been caused by end-of-file condition, additionally sets the eof indicator (see feof()) on stream. If the failure has been caused by some other error, sets the error indicator (see ferror()) on stream.

-

Example

#include <stdio.h>
-#include <stdlib.h>
- 
-int main(void)
-{
-    const char* fname = "/tmp/unique_name.txt"; // or tmpnam(NULL);
-    int is_ok = EXIT_FAILURE;
- 
-    FILE* fp = fopen(fname, "w+");
-    if (!fp) {
-        perror("File opening failed");
-        return is_ok;
-    }
-    fputs("Hello, world!\n", fp);
-    rewind(fp);
- 
-    int c; // note: int, not char, required to handle EOF
-    while ((c = fgetc(fp)) != EOF) // standard C I/O file reading loop
-        putchar(c);
- 
-    if (ferror(fp))
-        puts("I/O error when reading");
-    else if (feof(fp)) {
-        puts("End of file is reached successfully");
-        is_ok = EXIT_SUCCESS;
-    }
- 
-    fclose(fp);
-    remove(fname);
-    return is_ok;
-}

Possible output:

-
Hello, world!
-End of file is reached successfully
