Description
Variables
Compile time options. Statistics are kept about memory usage.
buffer_stat_nb
show how many buffers were created.
buffer_stat_alloc_bytes
show how many bytes were allocated.
Typesstructbuf
character array buffer. Consists of the following fields:
char*data
actual character data.
size_tsize
size of the string.
size_tasize
allocated size (0 = volatile buffer).
size_tunit
reallocation unit size (0 = read-only buffer).
intref
reference count.
Macros
CONST_BUF
create a global buffer name from a string literal string.
VOLATILE_BUF
create a volatile buffer name on the stack from a string strname.
BUFPUTSL
optimized bufputs() of a string literal.
Functionsbufcasecmp()
compare two buffers ignoring case.
bufcmp()
compare two buffers.
bufcmps()
compare a buffer to a string.
bufdup()
duplicate a buffer src.
bufgrow()
increase the allocated size to the given value.
bufnew()
create a new buffer.
bufnullterm()
terminate the string array by NUL (making a C-string).
bufprintf()
print formatted output to a buffer buf.
bufput()
append raw data to a buffer buf.
bufputs()
append a NUL-terminated string str to a buffer buf.
bufputc()
append a single char c to a buffer buf.
bufrelease()
decrease the reference count and free the buffer buf if needed.
bufreset()
free internal data of the buffer buf.
bufset()
safely assign a buffer to another.
bufslurp()
remove a given number of bytes from the head of the array.
buftoi()
convert the numbers at the beginning of the buffer buf into an int.
vbufprintf()
stdarg(3) variant of formatted printing into a buffer buf.

Return Values
The bufcasecmp(), bufcmp() and bufcmps() functions return an integer less than, equal to, or greater than
zero if a is found, respectively, to be less than, to match, or be greater than b.
The bufdup() and bufnew() functions return a structbuf* on success; on error they return NULL.
The bufgrow() function returns on success 1; on error - 0.
The bufnullterm(), bufprintf(), bufput(), bufputs(), bufputc(), bufrelease(), bufreset(), bufset(),
bufslurp() and vbufprintf() functions do not return a value.
The buftoi() function return the converted value.
