strcmp	reentrant	Compares two strings.
strcpy	reentrant	Copies one string to another.
strcspn	reentrant	Returns the index of the first character in a string that matches any character in a second string.
strlen	reentrant	Returns the length of a string.
strncat	reentrant	Concatenates up to a specified number of characters from one string to another.
strncmp	reentrant	Compares two strings up to a specified number of characters.
strncpy	reentrant	Copies up to a specified number of characters from one string to another.
strpbrk	reentrant	Returns a pointer to the first character in a string that matches any character in a second string.
strpos	reentrant	Returns the index of the first occurrence of a specified character in a string.
strrchr	reentrant	Returns a pointer to the last occurrence of a specified character in a string.
strrpbrk	reentrant	Returns a pointer to the last character in a string that matches any character in a second string.
strrpos	reentrant	Returns the index of the last occurrence of a specified character in a string.
strspn	reentrant	Returns the index of the first character in a string that does not match any character in a second string.
strstr	reentrant	Returns a pointer in a string that is identical to a second sub-string.

The string routines are implemented as functions and are prototyped in the string.h include file. They perform the following operations:

All string functions operate on null-terminated character strings. Use the buffer manipulation routines to work on non-terminated strings.
