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.
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.
[edit] 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[edit] References
