/* File : strrchr.c
|
|
Author : Richard A. O'Keefe.
|
|
Updated: 10 April 1984
|
|
Defines: strrchr(), rindex()
|
|
|
|
strrchr(s, c) returns a pointer to the last place in s where c
|
|
occurs, or NullS if c does not occur in s. This function is called
|
|
rindex in V7 and 4.?bsd systems; while not ideal the name is clearer
|
|
than strrchr, so rindex remains in strings.h as a macro. NB:
|
|
strrchr looks for single characters, not for sets or strings. The
|
|
parameter 'c' is declared 'int' so it will go in a register; if your
|
|
C compiler is happy with register char change it to that.
