NAME

fileread() - reads file into buffer

SYNOPSIS

int fileread(f,buf,size)
FILE *f;
char *buf;
int size;

DESCRIPTION

fileread() reads up to size bytes from the file into buf. The number actually read may be smaller if end-of-file is reached. The file pointer (implied) is left pointing to one past the last character read.

RETURNS

> 0: the number of bytes actually read.
= 0: file was at end-of-file.
< 0: error code.

It returns the number of bytes actually read or an error code.

NOTES

The buffer must be at least size long. If reading from a "raw" device, size must be a multiple of 512.
