Functions | |
int | av_strstart (const char *str, const char *pfx, const char **ptr) |
Return non-zero if pfx is a prefix of str. | |
int | av_stristart (const char *str, const char *pfx, const char **ptr) |
Return non-zero if pfx is a prefix of str independent of case. | |
char * | av_stristr (const char *haystack, const char *needle) |
Locate the first case-independent occurrence in the string haystack of the string needle. | |
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. | |
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. | |
size_t | av_strlcatf (char *dst, size_t size, const char *fmt,...) |
Append output to a string, according to a format. | |
char * | av_d2str (double d) |
Convert a number to a av_malloced string. | |
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. |
char* av_d2str | ( | double | d | ) |
Convert a number to a av_malloced string.

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 |

int av_stristart | ( | const char * | str, | |
const char * | pfx, | |||
const char ** | ptr | |||
) |
Return non-zero if pfx is a prefix of str independent of case.
If it is, *ptr is set to the address of the first character in str after the prefix.
str | input string | |
pfx | prefix to test | |
ptr | updated if the prefix is matched inside str |

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 |

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 |
WARNING: since the return value use the length of src and dst, these absolutely _must_ be a properly 0-terminated strings, otherwise this will read beyond the end of the buffer and possibly crash.

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 |
Definition at line 82 of file avstring.c.
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 |
WARNING: since the return value is the length of src, src absolutely _must_ be a properly 0-terminated string, otherwise this will read beyond the end of the buffer and possibly crash.

int av_strstart | ( | const char * | str, | |
const char * | pfx, | |||
const char ** | ptr | |||
) |
Return non-zero if pfx is a prefix of str.
If it is, *ptr is set to the address of the first character in str after the prefix.
str | input string | |
pfx | prefix to test | |
ptr | updated if the prefix is matched inside str |
