read() problem

[yay4rei]

I am writing an emulator for the Apple II, but when I try to read() a file into an array:
int load_roms(unsigned char userom[])
{
FILE *romfile; /* Create pointer to ROM file */
romfile=fopen(userom,"r"); /* Load apple.rom read-only */
if (!romfile) /* Check for problems opening the file */
{
printf("Cannot read %s \n", userom);
return 1;
}
int errcheck = read(romfile, &memory[0xF000], 1024);
if(errcheck = -1)
{
printf("ROM-File read error \n");
}
else printf("Bytes Read: %i \n", errcheck);

fclose(romfile); /*Close romfile */
return 0;
}

it returns -1! What am I doing wrong?

if (errchk == -1)...

The comparison operator is == not =.
