strncat

NEAR SYNTAX: char *_n_strncat( char *dst, char *src, unsigned int n );

FAR SYNTAX: char far * _f_strncat( char far * dst, char far * src, size_t n );

NOTE	By default, strncat() is defined to _n_strncat().

Description

Appends one string to another up to and including the null terminator or until n characters are transferred, followed by a null terminator.

For Rabbit 4000+ users, this function supports FAR pointers. By default the near version of the function is called. The macro USE_FAR_STRING will change all calls to functions in this library to their far versions. The user may also explicitly call the far version with _f_strfunc where strfunc is the name of the string function.

Because FAR addresses are larger, the far versions of this function will run slightly slower than the near version. To explicitly call the near version when the USE_FAR_STRING macro is defined and all pointers are near pointers, append _n_ to the function name, e.g., _n_strfunc. For more information about FAR pointers, see the Dynamic C User's Manual or the samples in Samples/Rabbit4000/FAR/.

Parameters

dst

Pointer to location to receive string.

src

Pointer to location to supply string.

n

Maximum number of bytes to copy. If equal to zero, this function has no effect.

Return value

Pointer to destination string.

Library

STRING.LIB
