Function Documentation

suffix_get_dest_name()

char* suffix_get_dest_name

(

const char *

src_name

)

Get the name of the destination file.

Depending on the global variable opt_mode, this tries to find a matching counterpart for src_name. If the name can be constructed, it is allocated and returned (caller must free it). On error, a message is printed and NULL is returned.

Definition at line 373 of file suffix.c.

{
    assert(src_name != NULL);
 
    // Length of the name is needed in all cases to locate the end of
    // the string to compare the suffix, so calculate the length here.
    const size_t src_len = strlen(src_name);
 
    return opt_mode == MODE_COMPRESS
            ? compressed_name(src_name, src_len)
            : uncompressed_name(src_name, src_len);
}

suffix_set()

void suffix_set

(

const char *

suffix

)

Set a custom filename suffix.

This function calls xstrdup() for the given suffix, thus the caller doesn't need to keep the memory allocated. There can be only one custom suffix, thus if this is called multiple times, the old suffixes are freed and forgotten.

Definition at line 388 of file suffix.c.

{
    // Empty suffix and suffixes having a directory separator are
    // rejected. Such suffixes would break things later.
    if (suffix[0] == '\0' || has_dir_sep(suffix))
        message_fatal(_("%s: Invalid filename suffix"), suffix);
 
    // Replace the old custom_suffix (if any) with the new suffix.
    free(custom_suffix);
    custom_suffix = xstrdup(suffix);
    return;
}
