strcpy

Declaration: char * strcpy (char * s1 , const char * s2 )
Category(ies): Strings
Description: Copies the string pointed to by s2 to the buffer pointed to by s1 . If the
objects pointed to by s1 and s2 overlap in memory, the behavior is
undefined.
s1 — Buffer to copy to.
Inputs:
s2 — String to be copied into s1.
Outputs: Returns the value of s1.
Assumptions: s1 points to a buffer large enough to hold s2.
Side Effects: None
Availability: All versions of the TI-89 / TI-92 Plus.
TI-89 / TI-92 Plus
Differences: None

Example:
void gr_seq_axes_lbl( SBYTE ax, char buf[] )
/* Create requested string in buf for sequence axes labels.
input: ax = -1 = n
= 0 = u
> 0 = u1 - u99
buf = buffer for string
*/
{
if( ax < 0 )
strcpy( buf, "n" );
else
{
strcpy( buf, "u" );
if( ax )
sprintf( buf + 1, "%d", (BYTE)ax );
}
}
