strchr

NEAR SYNTAX: char * _n_strchr( char * src, char ch );

FAR SYNTAX: char far * _f_strchr( char far * src, char ch );

NOTE	By default, strchr() is defined to _n_strchr().

Description

Scans a string for the first occurrence of a given character.

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

src

String to be scanned.

ch

Character to search

Return value

Pointer to the first occurrence of ch in src.
Null if ch is not found.
