|
|
.SH SYNTAX
|
|
.B #include <libowfat/byte.h>
|
|
|
|
size_t \fBbyte_chr\fP(const char *\fIhaystack\fR,size_t \fIlen\fR,char \fIneedle\fR);
|
|
.SH DESCRIPTION
|
|
\fIbyte_chr\fR returns the smallest integer \fIi\fR between 0 and
|
|
\fIlen\fR-1 inclusive such that \fIone\fR[\fIi\fR] equals \fIneedle\fR.
|
|
|
|
If no such integer exists, byte_chr returns \fIlen\fR.
|
|
|
|
byte_chr may read all bytes \fIone\fR[0], \fIone\fR[1], ...,
|
|
\fIone\fR[\fIlen\fR-1], even if not all the bytes are relevant to the
|
|
answer.
