strspn

NEAR SYNTAX: size_t _n_strspn( char * src, char * brk );

FAR SYNTAX: size_t _f_strspn( char far * src, char far * brk );

NOTE	By default, strspn() is defined to _n_strspn().

Description

Scans a string for the first segment in src containing only characters specified in brk.

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/.

String to be scanned
