char* av_stristr | ( | const char * | haystack, |
const char * | needle | ||
) |
Locate the first case-independent occurrence in the string haystack of the string needle.
A zero-length string needle is considered to match at the start of haystack.
This function is a case-insensitive version of the standard strstr().
haystack | string to search in |
needle | string to search for |

char* av_strnstr | ( | const char * | haystack, |
const char * | needle, | ||
size_t | hay_length | ||
) |
Locate the first occurrence of the string needle in the string haystack where not more than hay_length characters are searched.
A zero-length string needle is considered to match at the start of haystack.
This function is a length-limited version of the standard strstr().
haystack | string to search in |
needle | string to search for |
hay_length | length of string to search in |

size_t av_strlcpy | ( | char * | dst, |
const char * | src, | ||
size_t | size | ||
) |
Copy the string src to dst, but no more than size - 1 bytes, and null-terminate dst.
This function is the same as BSD strlcpy().
dst | destination buffer |
src | source string |
size | size of destination buffer |

size_t av_strlcat | ( | char * | dst, |
const char * | src, | ||
size_t | size | ||
) |
Append the string src to the string dst, but to a total length of no more than size - 1 bytes, and null-terminate dst.
This function is similar to BSD strlcat(), but differs when size <= strlen(dst).
dst | destination buffer |
src | source string |
size | size of destination buffer |

size_t av_strlcatf | ( | char * | dst, |
size_t | size, | ||
const char * | fmt, | ||
... | |||
) |
Append output to a string, according to a format.
Never write out of the destination buffer, and always put a terminating 0 within the buffer.
dst | destination buffer (string to which the output is appended) |
size | total size of the destination buffer |
fmt | printf-compatible format string, specifying how the following parameters are used |
size_t char* av_d2str | ( | double | d | ) |
Convert a number to a av_malloced string.
Definition at line 111 of file avstring.c.
char* av_get_token | ( | const char ** | buf, |
const char * | term | ||
) |
Unescape the given string until a non escaped terminating char, and return the token corresponding to the unescaped string.
The normal \ and ' escaping is supported. Leading and trailing whitespaces are removed, unless they are escaped with '\' or are enclosed between ''.
buf | the buffer to parse, buf will be updated to point to the terminating char |
term | a 0-terminated list of terminating chars |
