* Name: strchrnul
|
|
*
|
|
* Description:
|
|
* The strchrnul() function locates the first occurrence of 'c' (converted
|
|
* to a char) in the string pointed to by 's'. The terminating null byte is
|
|
* considered to be part of the string.
|
|
*
|
|
* Returned Value:
|
|
* Upon completion, strchrnul() returns a pointer to the byte, or a
|
|
* pointer to null if the byte was not found.
