Detailed Description

Function Documentation

void filename_sanitize ( char *  str)

Remove forbidden, potentially forbidden and otherwise evil characters from filenames.

This includes slashes, and popular characters like colon (on Unix anyway), so this should only be used for automatically generated filenames.

Warning
Do not use this on full paths, only single file names without any directory separator!

char* str_format_meta ( input_thread_t ,

char* str_format_time ( const char *  tformat)

Formats current time into a heap-allocated string.

Parameters
tformattime format (as with C strftime())
Returns
an allocated string (must be free()'d), or NULL on memory error.

static int vlc_ascii_strcasecmp ( const char *  psz1,
const char *  psz2 
)
inlinestatic

Compare two ASCII strings ignoring case.

The result is independent of the locale. If there are non-ASCII characters in the strings, their cases are NOT ignored in the comparison.

void vlc_xml_decode ( char *  st)

Decodes XML entities.

Decodes a null-terminated UTF-8 string of XML character data into a regular nul-terminated UTF-8 string. In other words, replaces XML entities and numerical character references with the corresponding characters.

This function operates in place (the output is always of smaller or equal length than the input) and always succeeds.

Parameters
strnull-terminated string [IN/OUT]

References cmp_entity(), xml_entity_s::psz_char, xml_entity_s::psz_entity, psz_value, and xml_entities.

char* vlc_xml_encode ( const char *  str)

Encodes XML entites.

Substitutes unsafe characters in a null-terminated UTF-8 strings with an XML entity or numerical character reference.

Parameters
strnull terminated UTF-8 string
Returns
On success, a heap-allocated null-terminated string is returned. If the input string was not a valid UTF-8 sequence, NULL is returned and errno is set to EILSEQ. If there was not enough memory, NULL is returned and errno is to ENOMEM.
