.SH NAME
|
|
str_diffn \- compare two ASCIIZ strings
|
|
.SH SYNTAX
|
|
.B #include <libowfat/str.h>
|
|
|
|
int \fBstr_diffn\fP(const char* \fIa\fR,const char* \fIb\fR,size_t \fIlimit\fR);
|
|
.SH DESCRIPTION
|
|
\fBstr_diffn\fR returns negative, 0, or positive, depending on whether the
|
|
string \fIa\fR[0], \fIa\fR[1], ..., \fIa\fR[n]=='\\0' is
|
|
lexicographically smaller than, equal to, or greater than the string
|
|
\fIb\fR[0], \fIb\fR[1], ..., \fIb\fR[m-1]=='\\0'.
|
|
|
|
If the strings are different, str_diffn does not read bytes past the
|
|
first difference. The strings will be considered equal if the first
|
|
\fIlimit\fR characters match.
