str_diffn(3) DragonFly Library Functions Manual str_diffn(3)
NAME
str_diffn - compare two ASCIIZ strings
SYNTAX
#include <str.h>
int str_diffn(const char* a,const char* b,size_t limit);
DESCRIPTION
str_diffn returns negative, 0, or positive, depending on whether the
string a[0], a[1], ..., a[n]=='\0' is lexicographically smaller than,
equal to, or greater than the string b[0], b[1], ..., b[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
limit characters match.
