stringprep_4i(3) -- Linux man page

NAME

SYNOPSIS

int stringprep_4i(uint32_t * ucs4, size_t * len, size_t maxucs4len, Stringprep_profile_flags flags, const Stringprep_profile * profile);  

ARGUMENTS

uint32_t * ucs4

 input/output array with string to prepare.

size_t * len

 on input, length of input array with Unicode code points, on exit, length of output array with Unicode code points.

size_t maxucs4len

 maximum length of input/output array.

Stringprep_profile_flags flags

 stringprep profile flags, or 0.

const Stringprep_profile * profile

 pointer to stringprep profile to use.

DESCRIPTION

The input is not required to be zero terminated ( ucs4 [ len ] = 0). The output will not be zero terminated unless ucs4 [ len ] = 0. Instead, see stringprep_4zi()
 if your input is zero terminated or if you want the output to be.

Since the stringprep operation can expand the string, maxucs4len indicate how large the buffer holding the string is. This function will not read or write to code points outside that size.

The flags are one of Stringprep_profile_flags, or 0.

The profile contain the instructions to perform. Your application can define new profiles, possibly re-using the generic stringprep tables that always will be part of the library, or use one of the currently supported profiles.
