Sh SYNOPSIS
In strings.h
Ft int
Fn bcmp "const void *b1" "const void *b2" "size_t len"
Ft void
Fn bcopy "const void *src" "void *dst" "size_t len"
Ft void
Fn bzero "void *b" "size_t len"
Ft int
Fn ffs "int value"
Ft char *
Fn index "const char *s" "int c"
Ft char *
Fn rindex "const char *s" "int c"
Ft int
Fn strcasecmp "const char *s1" "const char *s2"
Ft int
Fn strncasecmp "const char *s1" "const char *s2" "size_t len"
Sh DESCRIPTION
These functions all live in the
In strings.h
header file.
Except for
Fn ffs ,
they operate on strings.
Fn index ,
Fn rindex ,
and
Fn strcasecmp
need nul-terminated strings.
Pp
See the specific manual pages for more information.
Pp
See
Xr string 3
for string functions that follow
St -ansiC
or
St -isoC-99 ,
Xr bstring 3
for functions that operate on strings that are not nul-terminated, and
Xr bitstring 3
for bit-string manipulation macros.
