wstr_from_current

NAME

wstr_to_ascii - wide string handling functions

SYNOPSIS

 #include <synce.h>
 
 char *wstr_to_ascii(LPCWSTR unicode);
 char *wstr_to_utf8(LPCWSTR unicode);
 char *wstr_to_current(LPCWSTR unicode);
 
 LPWSTR wstr_from_ascii(const char * ascii);
 LPWSTR wstr_from_utf8(const char * utf8);
 LPWSTR wstr_from_current(const char * utf8);
 
 void wstr_free_string(void * string);
 
 size_t wstrlen(LPCWSTR unicode);
 
 LPWSTR wstrcpy(LPWSTR dest, LPCWSTR src);
 
 bool wstr_append(LPWSTR dest, LPCWSTR src, size_t max_dest_length);
 
 bool wstr_equal(LPWSTR a, LPWSTR b);
 
 LPWSTR wstrdup(LPCWSTR string);
 
 

DESCRIPTION

The wstr_to_xxx() functions convert a wide char string to the appropriate local string. The wstr_from_xxx() functions do the reverse. Use wstr_free_string() to free memory allocated for wide strings.

wstrcpy() requires that dest is large enough to contain src. No bounds checking is performed.

wstr_append() requires that dest is at least max_dest_length long. No bounds checking is performed.

The remaining functions perform standard string operations on wide char strings.

RETURN VALUE

wstr_to_xxx(), wstr_from_xxx(), wstrdup() return pointers to allocated strings. wstrlen() returns the string length. wstrcpy() returns the pointer to src.

wstr_append() returns false on failure eg. if the sum of the lengths is greater than max_dest_length, true on success.

wstr_equal() returns true if a and b are equal, false otherwise..
