63 | .SH DESCRIPTION | |
64 | The byte string functions perform operations on strings (byte arrays) | |
c13182ef MK |
65 | that are not necessarily null-terminated. |
66 | See the individual man pages | |
fea681da | 67 | for descriptions of each function. |
19c98696 | 68 | .SH NOTES |
fea681da MK |
69 | The functions |
70 | .BR bcmp (), | |
71 | .BR bcopy () | |
72 | and | |
73 | .BR bzero () | |
c13182ef MK |
74 | are obsolete. |
75 | Use | |
fea681da MK |
76 | .BR memcmp (), |
77 | .BR memcpy () | |
78 | and | |
79 | .BR memset () | |
80 | instead. | |
81 | .\" The old functions are not even available on some non-GNU/Linux systems. | |
