May be NULL in which 44 case the function will use its default regular expression 45 syntax type. 46 47 @param Result On return, points to TRUE if String fully matches against 48 the regular expression Pattern using the regular expression 49 SyntaxType. Otherwise, points to FALSE. 50 51 @param Captures A Pointer to an array of EFI_REGEX_CAPTURE objects to receive 52 the captured groups in the event of a match. The full 53 sub-string match is put in Captures[0], and the results of N 54 capturing groups are put in Captures[1:N]. If Captures is 55 NULL, then this function doesn't allocate the memory for the 56 array and does not build up the elements. It only returns the 57 number of matching patterns in CapturesCount. If Captures is 58 not NULL, this function returns a pointer to an array and 59 builds up the elements in the array. CapturesCount is also 60 updated to the number of matching patterns found. It is the 61 caller's responsibility to free the memory pool in Captures 62 and in each CapturePtr in the array elements. 63 64 @param CapturesCount On output, CapturesCount is the number of matching patterns 65 found in String. Zero means no matching patterns were found 66 in the string. 67 68 @retval EFI_SUCCESS The regular expression string matching 69 completed successfully. 70 @retval EFI_UNSUPPORTED The regular expression syntax specified by 71 SyntaxType is not supported by this driver. 72 @retval EFI_DEVICE_ERROR The regular expression string matching 73 failed due to a hardware or firmware error. 74 @retval EFI_INVALID_PARAMETER String, Pattern, Result, or CapturesCountis 75 NULL. 76 77 **/ 78 EFI_STATUS 79 EFIAPI 80 RegularExpressionMatch ( 81 IN EFI_REGULAR_EXPRESSION_PROTOCOL *This, 82 IN CHAR16 *String, 83 IN CHAR16 *Pattern, 84 IN EFI_REGEX_SYNTAX_TYPE *SyntaxType, OPTIONAL 85 OUT BOOLEAN *Result, 86 OUT EFI_REGEX_CAPTURE **Captures, OPTIONAL 87 OUT UINTN *CapturesCount 88 ); 89 90 /** 91 Returns information about the regular expression syntax types supported 92 by the implementation. 93 94 @param This A pointer to the EFI_REGULAR_EXPRESSION_PROTOCOL 95 instance. 96 97 @param RegExSyntaxTypeListSize On input, the size in bytes of RegExSyntaxTypeList. 98 On output with a return code of EFI_SUCCESS, the 99 size in bytes of the data returned in 100 RegExSyntaxTypeList.
