7.1.4 EFI_HII_PROTOCOL.TestString()<br />
Summary<br />
Test if all of the characters in a string have corresponding font characters.<br />
Prototype<br />
EFI_STATUS<br />
(EFIAPI *EFI_HII_TEST_STRING) (<br />
IN EFI_HII_PROTOCOL *This,<br />
IN CHAR16 *StringToTest,<br />
IN OUT UINT32<br />
*FirstMissing,<br />
OUT UINT32 *GlyphBufferSize<br />
);<br />
Parameters<br />
This<br />
StringToTest<br />
FirstMissing<br />
GlyphBufferSize<br />
A pointer to the EFI_HII_PROTOCOL instance.<br />
A pointer to a Unicode string.<br />
A pointer to an index into the string. On input, the index of the first<br />
character in the StringToTest to examine. On exit, the index of<br />
the first character encountered for which a glyph is unavailable. If all<br />
glyphs in the string are available, the index is the index of the<br />
terminator of the string.<br />
A pointer to a value. On output, if the function returns<br />
EFI_SUCCESS, this contains the amount of memory required to<br />
store the string’s glyph equivalent.<br />
Description<br />
This function may be repeatedly called to determine subsequent missing characters. Note that the index<br />
pointed to by FirstMissing must be incremented between calls. Line separator characters are<br />
ignored.<br />
Status Codes Returned<br />
EFI_SUCCESS<br />
EFI_NOT_FOUND<br />
All glyphs are available. (Note that an empty string always returns<br />
this value.)<br />
A glyph was not found for a character.<br />
