Functions | |
static bool | is_dir_sep (char c) |
Test if the char is a directory separator. | |
static bool | has_dir_sep (const char *str) |
Test if the string contains a directory separator. | |
static size_t | test_suffix (const char *suffix, const char *src_name, size_t src_len) |

Variables | |
static char * | custom_suffix = NULL |
Checks filename suffix and creates the destination filename.
static bool is_dir_sep | ( | char | c | ) | [static] |

static bool has_dir_sep | ( | const char * | str | ) | [static] |

static size_t test_suffix | ( | const char * | suffix, |
const char * | src_name, | ||
size_t | src_len | ||

static char* uncompressed_name | ( | const char * | src_name, |
const size_t | src_len | ||
) | [static] |
Removes the filename suffix of the compressed file.

static void msg_suffix | ( | const char * | src_name, |
const char * | suffix | ||
) | [static] |
This message is needed in multiple places in compressed_name(), so the message has been put into its own function.
References message_warning().
Referenced by compressed_name().
static char* compressed_name | ( | const char * | src_name, |
size_t | src_len | ||
) | [static] |
Appends suffix to src_name.
In contrast to uncompressed_name(), we check only suffixes that are valid for the specified file format.

Referenced by 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.
References compressed_name(), opt_mode, and uncompressed_name().
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.
