- Checks if the input string matches to the regular expression pattern.
-
- This A pointer to the EFI_REGULAR_EXPRESSION_PROTOCOL instance.
- Type EFI_REGULAR_EXPRESSION_PROTOCOL is defined in Section
- XYZ.
-
- String A pointer to a NULL terminated string to match against the
- regular expression string specified by Pattern.
-
- Pattern A pointer to a NULL terminated string that represents the
- regular expression.
-
- SyntaxType A pointer to the EFI_REGEX_SYNTAX_TYPE that identifies the
- regular expression syntax type to use. May be NULL in which
- case the function will use its default regular expression
- syntax type.
-
- Result On return, points to TRUE if String fully matches against
- the regular expression Pattern using the regular expression
- SyntaxType. Otherwise, points to FALSE.
-
- Captures A Pointer to an array of EFI_REGEX_CAPTURE objects to receive
- the captured groups in the event of a match. The full
- sub-string match is put in Captures[0], and the results of N
- capturing groups are put in Captures[1:N]. If Captures is
- NULL, then this function doesn't allocate the memory for the
- array and does not build up the elements. It only returns the
- number of matching patterns in CapturesCount. If Captures is
- not NULL, this function returns a pointer to an array and
- builds up the elements in the array. CapturesCount is also
- updated to the number of matching patterns found. It is the
- caller's responsibility to free the memory pool in Captures
- and in each CapturePtr in the array elements.
-
- CapturesCount On output, CapturesCount is the number of matching patterns
- found in String. Zero means no matching patterns were found
- in the string.
-
- @retval EFI_SUCCESS The regular expression string matching
- completed successfully.
- @retval EFI_UNSUPPORTED The regular expression syntax specified by
- SyntaxType is not supported by this driver.
- @retval EFI_DEVICE_ERROR The regular expression string matching
- failed due to a hardware or firmware error.
- @retval EFI_INVALID_PARAMETER String, Pattern, Result, or CapturesCountis
- NULL.
