curl_mprintf ()

    NAME

    curl_maprintf, curl_mfprintf, curl_mprintf, curl_msnprintf, curl_msprintf
    curl_mvaprintf, curl_mvfprintf, curl_mvprintf, curl_mvsnprintf,
    curl_mvsprintf - formatted output conversion
     
    

    SYNOPSIS

    #include <curl/mprintf.h>

    int curl_mprintf(const char *format, ...);
    int curl_mfprintf(FILE *fd, const char *format, ...);
    int curl_msprintf(char *buffer, const char *format, ...);
    int curl_msnprintf(char *buffer, size_t maxlength, const char *format, ...);
    int curl_mvprintf(const char *format, va_list args);
    int curl_mvfprintf(FILE *fd, const char *format, va_list args);
    int curl_mvsprintf(char *buffer, const char *format, va_list args);
    int curl_mvsnprintf(char *buffer, size_t maxlength, const char *format, va_list args);
    char *curl_maprintf(const char *format, ...);
    char *curl_mvaprintf(const char *format, va_list args);  

    DESCRIPTION

    These are all functions that produces output according to a format string and given arguments. These are mostly clones of the well-known C-style functions and there will be no detailed explanation of all available formatting rules and usage here.

    See this table for notable exceptions.

    curl_mprintf()
    Normal printf() clone.
    curl_mfprintf()
    Normal fprintf() clone.
    curl_msprintf()
    Normal sprintf() clone.
    curl_msnprintf()
    snprintf() clone. Many systems don't have this. It is just like sprintf but with an extra argument after the buffer that specifies the length of the target buffer.
    curl_mvprintf()
    Normal vprintf() clone.
    curl_mvfprintf()
    Normal vfprintf() clone.
    curl_mvsprintf()
    Normal vsprintf() clone.
    curl_mvsnprintf()
    vsnprintf() clone. Many systems don't have this. It is just like vsprintf but with an extra argument after the buffer that specifies the length of the target buffer.
    curl_maprintf()
    Like printf() but returns the output string as a malloc()ed string. The returned string must be free()ed by the receiver.
    curl_mvaprintf()
    Like curl_maprintf() but takes a va_list pointer argument instead of a variable amount of arguments.

    To easily use all these cloned functions instead of the normal ones, #define _MPRINTF_REPLACE before you include the <curl/mprintf.h> file. Then all the normal names like printf, fprintf, sprintf etc will use the curl-functions instead.  

    AVAILABILITY

    These function will be removed from the public libcurl API in a near future. They will instead be made "available" by source code access only, and then as curlx_-prefixed functions. See lib/README.curlx for further details.  

    RETURN VALUE

    The curl_maprintf and curl_mvaprintf functions return a pointer to a newly allocated string, or NULL it it failed.

    All other functions return the number of character they actually outputed.  

    SEE ALSO

    printf(3), sprintf(3), fprintf(3), vprintf(3)
