◆ TAILQ_HEAD()

TAILQ_HEAD ( AddressList  ,
Address   
)

◆ mutt_addr_cat()

void mutt_addr_cat ( char *  buf,
size_t  buflen,
const char *  value,
const char *  specials 
)

Copy a string and wrap it in quotes if it contains special characters.

Parameters
bufBuffer for the result
buflenLength of the result buffer
valueString to copy
specialsCharacters to lookup

This function copies the string in the "value" parameter in the buffer pointed to by "buf" parameter. If the input string contains any of the characters specified in the "specials" parameters, the output string is wrapped in double quoted. Additionally, any backslashes or quotes inside the input string are backslash-escaped.
