Defines: strstr()
|
|
22 |
||
23 |
strstr(src, pat) looks for an instance of pat in src. pat is not a
|
|
24 |
regex(3) pattern, it is a literal string which must be matched exactly.
|
|
25 |
The result is a pointer to the first character of the located instance,
|
|
26 |
or NullS if pat does not occur in src.
