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.
