.TH BSTRING 3 "4 March 1983" .SH NAME bcopy, bcmp, bzero \- byte string operations .SH SYNOPSIS .nf .B bcopy(b1, b2, length) .B char *b1, *b2; .B int length; .PP .B bcmp(b1, b2, length) .B char *b1, *b2; .B int length; .PP .B bzero(b, length) .B char *b1; .B int length; .fi .SH DESCRIPTION These functions operate on variable length strings of bytes. They do not check for null bytes as the routines in .IR string (3) do. .PP .I Bcopy copies .I length bytes from string .I b1 to the string .IR b2 . .PP .I Bcmp compares byte string .I b1 against byte string .IR b2 , returning zero if they are identical, non-zero otherwise. Both strings are assumed to be .I length bytes long. .PP .I Bzero places .I length 0 bytes in the string .IR b1 . .SH BUGS The .I bcmp and .I bcopy routines take parameters backwards from .I strcmp and .IR strcpy .
