- The header <string.h> declares one type and several functions, and defines
- one macro useful for manipulating arrays of character type and other objects
- treated as arrays of character type. Various methods are used for
- determining the lengths of the arrays, but in all cases a char * or void *
- argument points to the initial (lowest addressed) character of the array. If
- an array is accessed beyond the end of an object, the behavior is undefined.
-
- Where an argument declared as size_t n specifies the length of the array for
- a function, n can have the value zero on a call to that function. Unless
- explicitly stated otherwise in the description of those functions, pointer
- arguments on such a call must still have valid values.
-
- For all functions declared in this header, each character shall be
- interpreted as if it had the type unsigned char (and therefore every possible
- object representation is valid and has a different value).
-
- The following macros are defined in this file:<BR>
- @verbatim
- NULL
- bcopy(a,b,c) ( memcpy((void *)b, (const void *)a, (size_t)c))
- bcmp(a,b,c) ( memcmp((void *)a, (void *)b, (size_t)c))
- @endverbatim
-
- The following types are defined in this file:<BR>
- @verbatim
- size_t Unsigned integer type of the result of the sizeof operator.
