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.
