Macro Definition Documentation

◆ MHD_STATICSTR_LEN_

#define MHD_STATICSTR_LEN_ (   macro)    (sizeof(macro)/sizeof(char) - 1)

Determine length of static string / macro strings at compile time.

Definition at line 45 of file mhd_str.h.

◆ MHD_str_has_s_token_caseless_

#define MHD_str_has_s_token_caseless_ (   str,
  tkn 
)    MHD_str_has_token_caseless_((str),(tkn),MHD_STATICSTR_LEN_(tkn))

Check whether str has case-insensitive static tkn. Token could be surrounded by spaces and tabs and delimited by comma. Match succeed if substring between start, end of string or comma contains only case-insensitive token and optional spaces and tabs.

Warning
tkn must be static string
Parameters
strthe string to check
tknthe static string of token to find
Returns
non-zero if two strings are equal, zero otherwise.

Definition at line 113 of file mhd_str.h.

Function Documentation

◆ MHD_str_equal_caseless_()

int MHD_str_equal_caseless_ ( const char *  str1,
const char *  str2 
)

Check two string for equality, ignoring case of US-ASCII letters.

Parameters
str1first string to compare
str2second string to compare
Returns
non-zero if two strings are equal, zero otherwise.

◆ MHD_str_equal_caseless_n_()

int MHD_str_equal_caseless_n_ ( const char *const  str1,
const char *const  str2,
size_t  maxlen 
)

Check two string for equality, ignoring case of US-ASCII letters and checking not more than maxlen characters. Compares up to first terminating null character, but not more than first maxlen characters.

Parameters
str1first string to compare
str2second string to compare
maxlenmaximum number of characters to compare
Returns
non-zero if two strings are equal, zero otherwise.

◆ MHD_str_has_token_caseless_()

bool MHD_str_has_token_caseless_ ( const char *  str,
const char *const  token,
size_t  token_len 
)

Check whether str has case-insensitive token. Token could be surrounded by spaces and tabs and delimited by comma. Match succeed if substring between start, end of string or comma contains only case-insensitive token and optional spaces and tabs.

Warning
token must not contain null-charters except optional terminating null-character.
Parameters
strthe string to check
tokenthe token to find
token_lenlength of token, not including optional terminating null-character.
Returns
non-zero if two strings are equal, zero otherwise.

Check whether str has case-insensitive token. Token could be surrounded by spaces and tabs and delimited by comma. Match succeed if substring between start, end (of string) or comma contains only case-insensitive token and optional spaces and tabs.

Warning
token must not contain null-charters except optional terminating null-character.
Parameters
strthe string to check
tokenthe token to find
token_lenlength of token, not including optional terminating null-character.
Returns
non-zero if two strings are equal, zero otherwise.
