Appends characters from one string to another. | |
char * | strecpy (char *dst, const char *src, const char *last) |
Copies characters from one buffer to another. | |
char *CDECL | str_fmt (const char *str,...) |
void | str_validate (char *str, const char *last, bool allow_newlines, bool ignore) |
Scans the string for valid characters and if it finds invalid ones, replaces them with a question mark '?' (if not ignored). | |
void | str_strip_colours (char *str) |
Scans the string for colour codes and strips them. | |
void | strtolower (char *str) |
Convert a given ASCII string to lowercase. | |
bool | IsValidChar (WChar key, CharSetFilter afilter) |
Only allow certain keys. | |
int CDECL | seprintf (char *str, const char *last, const char *format,...) |
Safer implementation of snprintf; same as snprintf except:
| |
char * | md5sumToString (char *buf, const char *last, const uint8 md5sum[16]) |
Convert the md5sum to a hexadecimal string representation. | |
size_t | Utf8Decode (WChar *c, const char *s) |
size_t | Utf8Encode (char *buf, WChar c) |
size_t | Utf8TrimString (char *s, size_t maxlen) |
Properly terminate an UTF8 string to some maximum length. | |
char * | strndup (const char *s, size_t len) |
const char * | strcasestr (const char *haystack, const char *needle) |
Definition in file string.cpp.
bool IsValidChar | ( | WChar | key, | |
CharSetFilter | afilter | |||
) |
Only allow certain keys.
You can define the filter to be used. This makes sure no invalid keys can get into an editbox, like BELL.
key | character to be checked | |
afilter | the filter to use |

char* md5sumToString | ( | char * | buf, | |
const char * | last, | |||
const uint8 | md5sum[16] | |||
) |
Convert the md5sum to a hexadecimal string representation.
Convert the md5sum number to a 'hexadecimal' string, return next pos in buffer.
buf | buffer to put the md5sum into | |
last | last character of buffer (usually lastof(buf)) | |
md5sum | the md5sum itself |

char* strecat | ( | char * | dst, | |
const char * | src, | |||
const char * | last | |||
) |
Appends characters from one string to another.
Appends the source string to the destination string with respect of the terminating null-character and and the last pointer to the last element in the destination buffer. If the last pointer is set to NULL no boundary check is performed.
lastof() applies only to fixed size arrays
dst | The buffer containing the target string | |
src | The buffer containing the string to append | |
last | The pointer to the last element of the destination buffer |

Copies characters from one buffer to another.
Copies the source string to the destination buffer with respect of the terminating null-character and the last pointer to the last element in the destination buffer. If the last pointer is set to NULL no boundary check is performed.

void strtolower | ( | char * | str | ) |
Convert a given ASCII string to lowercase.
Convert the given string to lowercase, only works with ASCII!
NOTE: only support ASCII characters, no UTF8 fancy. As currently the function is only used to lowercase data-filenames if they are not found, this is sufficient. If more, or general functionality is needed, look to r7271 where it was removed because it was broken when using certain locales: eg in Turkish the uppercase 'I' was converted to '?', so just revert to the old functionality
