BYTE C-3


NAME



clrb, cmpb, movb, filb - perform byte operations

SYNOPSIS



clrb (loc, length)
char *loc;
int length;

cmpb (p1, p2, length)
char *p1;
char *p2;
int length;

movb (dest, source, length)
char *dest;
char *source;
int length;

filb (s, c, n)
char *s;
char c;
int n;

DESCRIPTION



Clrb zeros length bytes, starting at the pointer loc.

Cmpb compares its arguments and returns an integer greater than,
equal to or less than 0 according to whether p1 is
lexicographically greater than, equal to or less than p2. Cmpb
compares at most length bytes, but unlike strcmp(3), does not
stop upon reaching a zero byte.

Movb copies length bytes from source to dest.

Filb sets n bytes starting at s to character c.

NOTES



Cmpb uses native character comparison that may be signed or
unsigned depending on the C compiler on your system.
