.TH INTSTRLEN 3 libsimple .SH NAME INTSTRLEN \- get the maximum length of an integer string .SH SYNOPSIS .nf #include <libsimple.h> #ifndef INTSTRLEN # define INTSTRLEN(type) /* implementation omitted */ #endif .fi .SH DESCRIPTION The .BR INTSTRLEN () macro assumes .I type is an integer type, and expends to a value representing a number of bytes sufficiently large to store any value of the specified integer type as a string without leading zeroes or plus sign, and .IR "without a terminating NUL byte" , as a constant expression in the type .BR size_t ; however it is not suitable for .BR #if . .PP The resulting value can depend in either the type is signed or unsigned, and can be slightly larger than necessary, it can however not be smaller. (For integers up to 64 bits, the result is only off by one for signed 64-bit integer types.) .SH EXAMPLES None. .SH APPLICATION USAGE None. .SH RATIONALE None. .SH FUTURE DIRECTIONS None. .SH NOTES None. .SH BUGS None. .SH SEE ALSO .BR TYPE_MIN (3libsimple) .BR TYPE_MAX (3libsimple)
