Function Documentation

void usprep_close ( UStringPrepProfile profile  ) 

Closes the profile.

Parameters:
profile The profile to close
Stable:
ICU 2.8

UStringPrepProfile* usprep_open ( const char *  path,
const char *  fileName,
UErrorCode status 
)

Creates a StringPrep profile from the data file.

Parameters:
path string containing the full path pointing to the directory where the profile reside followed by the package name e.g. "/usr/resource/my_app/profiles/mydata" on a Unix system. if NULL, ICU default data files will be used.
fileName name of the profile file to be opened
status ICU error code in/out parameter. Must not be NULL. Must fulfill U_SUCCESS before the function call.
Returns:
Pointer to UStringPrepProfile that is opened. Should be closed by calling usprep_close()

int32_t usprep_prepare ( const UStringPrepProfile prep,
const UChar *  src,
int32_t  srcLength,
UChar *  dest,
int32_t  destCapacity,
int32_t  options,
UParseError parseError,
UErrorCode status 
)

Prepare the input buffer for use in applications with the given profile.

This operation maps, normalizes(NFKC), checks for prohited and BiDi characters in the order defined by RFC 3454 depending on the options specified in the profile.

Parameters:
prep The profile to use
src Pointer to UChar buffer containing the string to prepare
srcLength Number of characters in the source string
dest Pointer to the destination buffer to receive the output
destCapacity The capacity of destination array
options A bit set of options:

Parameters:
parseError Pointer to UParseError struct to receive information on position of error if an error is encountered. Can be NULL.
status ICU in/out error code parameter. U_INVALID_CHAR_FOUND if src contains unmatched single surrogates. U_INDEX_OUTOFBOUNDS_ERROR if src contains too many code points. U_BUFFER_OVERFLOW_ERROR if destCapacity is not enough
Returns:
The number of UChars in the destination buffer
