Function Documentation

svn_error_t* svn_hash_read (  apr_hash_t *    hash, apr_file_t *    srcfile, apr_pool_t *    pool )

Deprecated: Provided for backward compatibility with the 1.0 API. This function behaves like svn_hash_read2, but it only works on an apr_file_t input, empty files are accepted, and the hash is expected to be terminated with a line containing "END" or "PROPS-END".

svn_error_t* svn_hash_read2 (  apr_hash_t *    hash, svn_stream_t *    stream, const char *    terminator, apr_pool_t *    pool )

Since: New in 1.1. Read a hash table from stream, storing the resultants names and values in hash. Use a pool for all allocations. hash will have const char * keys and svn_string_t * values. If terminator is NULL, expect the hash to be terminated by the end of the stream; otherwise, expect the hash to be terminated by a line containing terminator. Pass SVN_HASH_TERMINATOR to use the conventional terminator "END".

svn_error_t* svn_hash_read_incremental (  apr_hash_t *    hash, svn_stream_t *    stream, const char *    terminator, apr_pool_t *    pool )

Since: New in 1.1. Similar to svn_hash_read2(), but allows stream to contain deletion lines which remove entries from hash as well as adding to it.

svn_error_t* svn_hash_write (  apr_hash_t *    hash, apr_file_t *    destfile, apr_pool_t *    pool )

Deprecated: Provided for backward compatibility with the 1.0 API. This function behaves like svn_hash_write2, but it only works on an apr_file_t output, and the terminator is always "END".

svn_error_t* svn_hash_write2 (  apr_hash_t *    hash, svn_stream_t *    stream, const char *    terminator, apr_pool_t *    pool )

Since: New in 1.1. Dump hash to stream. Use pool for all allocations. hash has const char * keys and svn_string_t * values. If terminator is not NULL, terminate the hash with a line containing terminator.

svn_error_t* svn_hash_write_incremental (  apr_hash_t *    hash, apr_hash_t *    oldhash, svn_stream_t *    stream, const char *    terminator, apr_pool_t *    pool )

Since: New in 1.1. Similar to svn_hash_write2(), but only writes out entries for keys which differ between hash and oldhash, and also writes out deletion lines for keys which are present in oldhash but not in hash.
