Description

strccpy() copies the input string, up to a null byte, to the output string, compressing the C-language escape sequences (for example, \n, \001) to the equivalent character. A null byte is appended to the output. The output argument must point to a space big enough to accommodate the result. If it is as big as the space pointed to by input it is guaranteed to be big enough. strccpy() returns the output argument.

strcadd() is identical to strccpy(), except that it returns the pointer to the null byte that terminates the output.

strecpy() copies the input string, up to a null byte, to the output string, expanding non-graphic characters to their equivalent C-language escape sequences (for example, \n, \001). The output argument must point to a space big enough to accommodate the result; four times the space pointed to by input is guaranteed to be big enough (each character could become \ and 3 digits). Characters in the exceptions string are not expanded. The exceptions argument may be zero, meaning all non-graphic characters are expanded. strecpy() returns the output argument.

streadd() is identical to strecpy(), except that it returns the pointer to the null byte that terminates the output.

Examples

/* expand all but newline and tab */
strecpy( output, input, "\n\t" );

/* concatenate and compress several strings */
cp = strcadd( output, input1 );
cp = strcadd( cp, input2 );
cp = strcadd( cp, input3 );

Notes

When compiling multi-thread applications, the _REENTRANT flag must be defined on the compile line. This flag should only be used in multi-thread applications.
